Item Adsorbents from Jatropha curcas Shells Production, Utilisation Equilibrium, Kinetics and Thermodynamic Studies of their Adsorption: A Review(The Society for the Conservation of Phytofuels and Sciences, 2012-09-01) Okeola, F. O.; Odebunmi, E. O.; Adebayo, G.B.; Ameen, O. M.Jatrophas curcas is a multipurpose non-edible oil bearing and draught hardy perennial shrub. It is becoming popular for its eco-restoration of degraded land and production of biodiesel. Although much has been reported about the use of the oil, the cake and the glycerine from the seed of this plant, maximum benefit can still be obtained if the waste by-products are fully exploited. The seed cake is used as organic manure. The shells which constitute 39 % of the seed and fruit pericarp, has been reported being used as raw-materials for the production of biosorbent utilized for adsorption. Adsorption is widely used as an effective physical method of eliminating or lowering the concentration of wide range of dissolved pollutants (organic, inorganic) in an effluent. In the review Jatropha curcas shells have either been used directly in powder form as adsorbent or converted through carbonization and activation to activated carbon a typical adsorbent. Equilibrium, kinetics and thermodynamic studies on these adsorbents, as well as their characterization were reported. Powdered jatrophas curcas seed coats have also been reported to be used as adsorbent to remove metal ions from waste water. Activated carbons prepared from the shells were also use to remove anions, heavy metals, organics and dyes from water by adsorption Thus Jatropha curcas shells adsorbents were found to serve as low cost, locally available, highly efficient and eco-friendly adsorbents.Item Adsorption of Cd(II) And Fe(II) from Aqueous Solution Using Adsorbents Prepared from Waste Polythene Sachets(2016) Adebayo, G.B.; Orimolade, B.O.; Saliu, O.D.; Abu, T.O.; Abdulsalam, K.The adsorption of Fe(II) and Cd(II) ions from aqueous solution was studied using adsorbents prepared from waste polythene sachets. The effect of initial ion concentration, contact time, pH, adsorbent dose and temperature on the removal of Fe(II) and Cd(II) ions wasexamined. The optimum concentration was found to be 40 ppm for Fe(II) and 50 ppm for Cd(II) ions. The equilibrium data fit the Langmuir isotherm better than the Freundlich and Temkinisotherms. The negative values of the Gibbs free energy (ΔG) revealed that the adsorption process is feasible and spontaneous. The adsorption of Cd(II) ion was found to be spontaneous at 323 K on sulfuric acid activated samples but not spontaneous at all on carbonized samples. The adsorption data fit well into the pseudo-second-order kinetic model and the experimental quantities of Cd(II) and Fe(II) adsorbed are relatively close to the calculated quantities adsorbed. The prepared adsorbents therefore offer an alternative for the removal of the metal ions from contaminated water.Item ADSORPTION OF PB(II) BY MODIFIED AND ACTIVATED CARBON PREPARED FROM Deniella oliveri STEM BARK(2016) Adebayo, G.B.; Adegoke, H.I.; Sidiq, F.Deniella oliveri stem bark was modified using citric acid and activated chemically in the Laboratory. The samples were characterized by physico-chemical and spectroscopic methods. The physico-chemical methods used include ash content, point of zero charge, pH, moisture content, bulk density, volatile component and iodine value while the spectroscopic methods used are X-ray fluorescence (XRF) and Scanning Electron microscopy. The prepared adsorbents were employed in adsorption of Pb(II) ion from aqueous solution and influence of some physicochemical parameters on the adsorption process were also investigated. The adsorption data fitted the Langmuir adsorption data better than the Freundlich isotherm with correlation coefficients of 0.988 and the result of kinetics studies revealed that the data followed the pseudo-second order best which implies that the adsorption process is a chemical process. The result of this study revealed that citric acid modified bark stem has a higher adsorption capacity when compared with the activated one.Item Adsorption Study of Utilizing Calabash (crescentia cujete) Seed in the Removal of Heavy Metals from Industrial Wastewater(2018-02) Amigun, A.T.; Jamiu, W.; Adebayo, G.B.; Jimoh, A.A.This work was carried out to assess the physicochemical parameters and removal of heavy metals from industrial wastewater by activated carbon prepared from calabash seed. Some physicochemical parameters of the wastewater that assessed are pH, temperature, and turbidity, BOD, COD, TS, TDS and TSS. Adsorption studies on the effects of contact time, pH and adsorbent doses on the removal of heavy metals were investigated. The pH and temperature of granite industrial wastewater were 7.5 and 32.5 respectively which are within the permissible limit of WHO (7-8.5 and 32 oC). The wastewater sample shows extremely high turbidity of 2.5 mg/l, biochemical oxygen demand (BOD) of 430 mg/l, chemical oxygen demand (COD) of 283 mg/l, total solid (TS) of 45 mg/l, total dissolved solid (TDS) of 655 mg/l and total suspended solid (TSS) of 965 which are above permissible limit of WHO. The maximum adsorption capacity of Zn (99%) and Fe (88%) were observed at pH 8 and 12 respectively. The pseudo-fist order and pseudo-second order kinetic models were used to fit the kinetic data of the adsorption process, and the result obtained showed that pseudo-second order kinetic model was able to fit the generated adsorption data from the heavy metals considered in this research work due to the regression coefficient R2 of 0.997 value obtained. The study reveals that granite industrial wastewater effluent is one of the industries responsible for polluting the surrounding aquatic environment.Item An Assessment of Heavy Metals Contents in the Soil around a Cement Factory in Ewekoro, Nigeria Using Pollution Indices(2017) Okoro, H.K.; Orimolade, B.O.; Adebayo, G.B.; Akande, B.A.; Ximba, B.J; Ngila, J.NThis study investigated the concentrations of heavy metals in soils around the WAPCO cement factory in Ewekoro in southwestern Nigeria. A total of 27 soil samples were collected from three locations (Ewekoro, Papalanto, and Itori) around the cement factory. Atomic absorption spectroscopy was used to determine the concentrations of metals. The results revealed that the mean values of the metals content in the three soil samples were in the order: Fe > Zn >Mn> Cr > Cu >Pb. The concentrations of Pb present in Ewekoro and Papalanto samples were 0.391 and 0.243 mg/kg, respectively while Pb was not found in the control area(Itori). The concentrations of the heavy metals in the soil samples were found to decrease as the distances of the communities from the cement factory increased. Our study revealed that study area soils were affected by dust emissions from the cement factory as shown in the very low concentrations of heavy metal contents of the control study area, Itori.Item Batch Sorption of Ciprofloxacin on Kaolinitic Clay and nHematite Composite Equilibrium and Thermodynamics Studies(2016-01) Adekola, F.A.; Adegoke, H.I; Adebayo, G.B.; Abdulsalam, I.O.In this study nanoparticles of hematite and hematite-kaolin composite were prepared and characterized using X-ray diffraction, X-ray fluorescence (XRF), Scanning electron microscopy (SEM), Fourier transform infra-red spectroscopy (FTIR) and UV-visible spectroscopy analysis. The prepared materials were applied for the sorption of Ciprofloxacin (CIP) from aqueous solution. The effects of contact time, initial CIP concentration, pH and temperature were experimentally studied in batch mode to evaluate the adsorption capacity, kinetics, thermodynamics and equilibrium. Under the established experimental conditions the adsorption reached equilibrium in about 60 minutes and the optimum adsorption capacity attained was 16 x10-6 mol/g between pH of 5and 9 for hematite-kaolin composite. Ciprofloxacin uptake per unit mass was found to decrease with increase in adsorbent dosage. The adsorption process was found to be exothermic.The dynamic drug uptake data were applied to various kinetic models and their order of fitness was found to be Pseudo-second order >Elovich equation > Intra-particle diffusion > Pseudo-first order. It was found that the data fitted best with Temkin>Dubinin-Radushkevich>Freundlich> Langmuir, as indicated by their regression values.Item Biosorption of Fe (II) and Cd (II) ions from aqueous solution using a low cost Adsorbent from Orange Peels(2016-09) Adebayo, G.B.; Mohammed, A.A.; Sokoya, S.O.The peels from orange are less expensive biomaterials with excellent adsorption capacities. Orange peels were carbonized at 450 ºC, purified, activated with orthophosphoric acid and modified with citric acid to obtain Modified and Activated carbon which were used as low cost adsorbent to adsorb Cd(II) and Fe(II) metal ions. The effects of initial metal ions concentration; pH; temperature; contact time; and adsorbents dose on the removal of metal ions were investigated. The maximum adsorption occurs at 26 ºC and decreased with increase in temperature while optimum adsorption took place at pH of 6. Both the Fe-MOP and Fe-AOP system attained equilibrium in 60 minutes but Cd-MOP & Cd-AOP attained equilibrium at 45mins. The enthalpy 0f adsorption ranged from 2.48 KJ/mol to 14.418 KJ/mol and the entropy of adsorption ranged from -3.53 KJ/mol to 41.07 KJ/mol for both adsorbents (MOP and AOP). The kinetic studies showed that the adsorption process fitted well for pseudo-second order rateexpression. Both MOP and AOP has much affinity for Fe(II) uptake than Cd(II) ion and the adsorption data fitted most into Freundlich but the highest adsorption capacity of 0.895 was obtained from Temkin. The presence of hydroxyl, alkyl, ether and aldehyde groups was confirmed by Infrared while the SEM shows porous surface characteristics suitable for adsorption.Item Characterization and Thermodynamics of a Natural Mineral Dye-Based Chromium Complex Dye on Cotton Fabric(2019) Adebayo, G.B.; Orimolade, B.O.; Adegoke, H.I.; Saliu, O.D.; Ajetomobi, O.O.Transition metal complex of a bisazo dye derived from p-phenylenediamine extracted from a natural mineral dye and p-nitroaniline was synthesized with the azo dye acting as ligand for the metal complex dye. The ligand, azo dye and the metal complex were characterized using UV-visible spectroscopy, IR spectroscopy and GC-MS. The IR spectroscopy of both the ligand and the complex reveal the presence of azo group (N=N) at 1597 cm-1, N-O at 1384 cm-1 and other Metal-Ligand (M-L) bonds at 418 cm-1. The results were used to establish the type of metal complex formed to be 1:1 (metal: ligand) and possible structure of the complex was proposed. The metal complex dye was applied on cotton fabric and the thermodynamics parameters of the dyeing process were determined. These parameters included the enthalpy change which was -58.94 KJmol-1 and the entropy which was 0.159 KJmol-1. The thermodynamics studies of the dye showed that the dye has high substantivity and fastness that can be useful in dyeing fabric.Item CHROMATOGRAPHIC SEPARATION AND SPECTRO-ANALYTICAL CHARACTERIZATION OF A NATURAL AFRICAN MINERAL DYE(2007) Adebayo, G.B.; Adekola, F.A.; Olatunji, G.A.Chromatographic fractionation and spectroscopic characterization of a natural African mineral dye have been carried out. The chromatographic separation of the dyes made use of column and thin layer chromatographic techniques. Some physicochemical properties of thedye including solubility in polar and non-polar solvents, pH, ash and organic contents were determined. The spectro-analytical techniques used for characterization included energy dispersive X-ray fluorescence (EDXRF), X-ray diffractometry (XRD), Optical microscopy, infrared (IR) and UV-VIS spectroscopy. Four different fractions having colours yellow, grey, orange and purple were obtained from the chromatographic separation. All the fractions were found to contain aromatic nucleus based on IR and UV-VIS spectroscopic data. Other functional groups detected are Ar-NH2, -CONH2, C=C, C-C and metal-carbon chelate rings. The presence of aromatic amine in the dye provides strong evidence for its use as hair dye. The dye was found to be soluble in both aqueous and non-aqueous solvents. The pH of the dye’s aqueous solution was found to be 8.6, and the ash and organic content of the raw dye were 49% and 51% respectively. The XRF revealed that the dye contains twenty elements with concentrations ranging from major to ultratrace levels. The XRD also showed that the sample contains about forty-six mineral phases which include both inorganic and organic components. The maximum absorption wavelength (•max) in UV-VIS of the aqueous solution was found to be 464 nm. The optical microscopic investigation gave indication that the dyes are likely to be of the marine origin.Item ECOTOXICOLOGICAL AND RISK ASSESSMENT OF GLYPHOSATE ON THE ACTIVITY OF DUCKWEED(2016-04-08) Adebayo, G.B.; Orimolade, B.O.; Okoro, H.K.; Orija, D.Ecotoxicological effect and risk assessment of a pesticide residue (glyphosate) was studied. The effect of different concentrations (0.2-0.8ppm) of glyphosate on the plant (Duckweed) was used for the study by collecting and culturing duckweed for a period of one week and thereafter exposing the duckweed to different concentrations of glyphosate for 8 days. The pigment content and biomass were monitored to assess the effects of the glyphosate on the plant. The results revealed that all the concentrations show adverse effect on the plant pigment content as well as on the biomass productivity as the days progressed and the concentration increases. This study has shown that the residue of glyphosate could be dangerous to the ecosystem at concentration as low as 0.2ppm which is actually the allowable level of glyphosate in plant leaf.Item Ecotoxicological and Risk Assessment of Hydroquinone Cream Residue on Duckweed Plants(2019-01) Adebayo, G.B.; Orimolade, B.O.; Okoro, H.K.; Banwo, M.A.Residues from personal care products have been reportedly found in soils and are harmful to plants and animals. This research studied the ecotoxicology effects and risk assessment of hydroquinone cream residue on duckweed plant. The effects of different concentrations (50, 100, 150 and 250 ppm) on the duckweed (Lemna minor) were used for the study. The duckweed was collected from the Dam area of University of Ilorin, Ilorin, Nigeria and cultured for a period of one week before using it for the study. The plants were exposed to the different concentrations of hydroquinone cream for a period of 8 days. The results revealed that all the concentration shows adverse effect on the plant pigment content as well as biomass with the effect increasing as the concentration increases. The study has shown that the residue of hydroquinone cream could be dangerous to the ecosystem at concentration as low as 50 ppm which is well below the amount of the residue expected in the environment.Item Ecotoxicological Assessment of Chromium (III) and Mercury (II) Ions on Pseudomonas aeruginosa Isolated from Kerosene Polluted Ilorin alfisol(Faculty of Physical Sciences and Faculty of Life Sciences, University of Ilorin Nigeria, 2016) Adebayo, G.B.; Adetitun, D.O.; Okoro, H.K.; Olohunseye, A.A.The effect of the heavy metal solution of different concentrations on P. aeruginosa was studied. Different concentrations of the heavy metal solution (5ppm, 20ppm and 50ppm) were spiked to a fixed volume of P. aeruginosa (broth). The changes on the growth of bacteria were monitored for 5days by measuring the optical density of the mixture at 600nm with spectrophotometer. The study revealed that high concentration of some trace heavy metals like Cr3+ and Hg2+ inhibit the growth of this bacterium. This is shown in the daily growth of the P. aeruginosa which kept reducing with an increase in the concentration of the heavy metals. The reduction was attributed to effect of high concentrations of the heavy metals that was taken up by the P. aeruginosa which is responsible for the observed inhibition of its growth. The potential harmful effect of these heavy metals can be seen from changes in turbidity of P. aeruginosa as the concentration of the heavy metals increases. These effects may also indirectly affect the aquatic animals leading to serious ecotoxicological hazard. Also, owing to the presence of heavy metals and some other pollutants the slight decrease in the growth of P. aeruginosa has been attributed to high concentration of heavy metals as a source of pollutants. Therefore, waste that contain either mercury or chromium as one of the major pollutants if discharged into water bodies without treatment may lead to devastating effects on the ecosystem.Item ECOTOXICOLOGICAL EFFECTS OF HYDROQUINONE COSMETIC ON GROWTH AND PIGMENT CONTENT OF SALVINIA CUCULLATTA (FERN PLANT)(Faculty of Pure and Applied Sciences, LAUTECH, Ogbomosho, 2015) Adebayo, G.B.; Okoro, H.K.; Oluyide, A.A.Study on the effects of different concentrations of (10ppm, 20ppm and 50ppm) hydroquinone solutions has been carried out on Salvinia Cucullata growth. The plants were cultured in a control with no hydroquinone and at different concentrations of hydroquinone solutions in the laboratory for a period of 8days. The toxicity symptoms, total chlorophyll content and biomass were determined at 2,4,6 and 8days.The results revealed significant (P ≤ 0.05) effects on chlorophyll contents. Plants in the control having the highest chlorophyll content) and biomass as the concentration increases (from 11.45g which is control to 5.79g which is 50 ppm). The result has shown that cosmetic products that contain 2% hydroquinone (20,000ppm) are likely to produce residue of about 50ppm and hence can be detrimental to the ecosystem.Item The Effect of Two African Mineral Dyes on the Activity of Alkaline Phosphatase in the Skin and Serum of Albino Rats(2006-09) Adebayo, G.B.; Sunmonu, T.O.; Adekola, F.A.; Olatunji, G.A.The effect of two African mineral dyes Yombo tumtum (YT) and Yombo fita (YF) on the activity of alkaline phosphatase (ALP) in the skin and serum of albino rats was investigated. The chemical analyses of the dyes were first carried out using solubility test, pH determination and X-ray fluorescence (XRF) elemental analysis. Six different concentrations (0.05, 0.15, 0.25, 0.5, 0.75 and 1.00%) of each dye were prepared using hydrogen peroxide as solvent. A total of 70 albino rats (Rattus norvegicus) were used for the study. The rats were grouped into 14 of 5 rats and were maintained on commercial feed for a period of 30 days, during which the experiment lasted. Group I served as the first control and the animals had distilled water applied on their heads. Group 2 which served as the second control contained rats on whose heads were applied the dissolving solvent i.e. hydrogen peroxide. Rats in group 3 to 8 had the various concentrations of YT (black) dye applied on their heads, while those in groups 9 to 14 had the various prepared concentrations of YF (white) dye applied on their heads. At the end of the experiment, blood samples were collected and portion of the head skin where the dyes were applied was cut. The activity of ALP was thereafter determined in the serum and skin of the experimental animals. The results revealed a significant decrease (p<0.05) in the activity of ALP as the concentration of the dye increased in both the serum and skin @JASEM.Item Effect of white African mineral hair dye on the activities of phosphatases and malondialdehyde level in selected tissues of albino rats(2005-09) Adebayo, G.B.; Sunmonu, T.O.; Adekola, F.A.; Olatunji, G.A.The effect of white African mineral dye Yombofita (YF) on the activities of alkaline phosphatase (ALP), acid phosphatase (ACP) and malondialdehyde (MDA) levels in the skin, liver, kidney and serum of albino rats was investigated. The chemical analysis of the dye was first carried out using solubility test, pH determination and X-ray fluorescence (XRF) elemental analysis. Six differentconcentrations (0.05, 0.15, 0.25, 0.5, 0.75 and 1.00%) of the dye were prepared using hydrogen peroxide (30 volume) as solvent. A total of 80 albino rats (Rattus norvegicus) were used for the study. The rats were divided into 8 groups of 10 each and were maintained on commercial feed for the period of the experiment i.e. 30 days. In group 1, the control group, the animals were applied distilled water on their heads, whereas in group 2 the vehicle i.e. hydrogen peroxide was applied. In groups 3 to 8 various concentrations of YF (white) dye ranging from 0.05, 0.15, 0.25, 0.5, 0.75 to 1.00% was applied respectively. At the end of the experiment, blood samples were collected and portions of the selected tissues were excised for the determination of ALP and ACP activities. The MDA level was also determined in the skin of experimental animals. The results revealed a significant decrease (p<0.05) with increasing concentration of the dye in the activities of ALP and ACP in the kidney and skin but not in the liver while the level of MDA in the skin increased significantly (p< 0.05) with increasing concentration of the dye.Item Exhaustive and Affinitive properties of a thiophene substituted triazenyl based reactive dye on cellulose acetate pthalate-co-polyethylene glycol biopolymer film(2018-05-24) Adebayo, G.B.; Saliu, D.O.; Arowona, M.T; Alabi, O.E.The experimental exhaustion performance of a triply coupled triazenyl based reactive dye was used to establish the affinitive properties of the dye on 1:1, 1:2 and 2:1 formulations of cellulose acetate phthalate (CAP) and poly (ethylene glycol) (PEG) blends. The dye whose physicochemical properties include a melting point of 173, theoretical yield of 73%, maximum wavelength of 535 nm and solubility in polar solvents was synthesized by doubly coupling it with 2-(aminomethyl)thiophene and singly coupled with 2-naphthol after diazotization.The maximum absorption peak at 535 nm ascertains the presence of conjugated double bond, functional groups such as hydroxyl and amino correspond to 3628 cm-1 and 1334 cm-1 respectively on the FTIR. The m/z = 415 confirms the breaking away of two ethyl thiophenyl cation while the fragmentation of the two residual amine groups is shown by the m/z value at 382 from the GC-MS. At 60°C, the first blend (CAP-PEG-1) has the highest degree of exhaustion of 89.92, partition coefficient of 180 (L-1), dye affinity of 14300 kJ/mol, while the third blend (CAP-PEG-3) has the highest degree of levelness.Item Mineral Characterization of Yombo-Fitta - An African Natural Hair Dye(2011) Adebayo, G.B.; Adekola, F.A; Olatunji, G.A.Mineral contents of an African hair dye were investigated. Some physiochemical properties such as solubility, pH, ash and organic content were first carried out. Combinations of XRF, XRD, SEM, IR, and UV-VISIBLE spectroscopic techniques were employed in the investigation. The dye was found to dissolve in all the ten aqueous and nonaqueous media used. The pH of the aqueous solution was found to be 8.6. Ash and organic contents of the raw dye were found to be 51% and 49% respectively. The XRF revealed that the dye contains twenty elements which include K, Ca, Ti, V, Cr, Zn, Mn, Fe, Co, Ni, Cu, As, Nb, Zr, Rb, Sr, Y, Mo and Br, with concentrations ranging from major to ultra-trace levels. The XRD also showed that the sample contains about forty six mineral phases which include both inorganic and organic components. The optical microscopic investigation gave indication that the dye was likely to be of the marine origin. The infrared (IR) measurements indicated that the sample contained functional groups such as C=O, C=C, C-C, CN, aromatic ring and metal-carbon chelate rings. The UV-VIS spectra show that the dye absorbed in the visible region with λmax of the aqueous solution being 464.0 nm.Item Physical modification of Nylon-6 for improving dyeing quality of selected acid dyes on fabrics and variation of their thermodynamic parameters(Faculty of Pure and Applied Sciences, LAUTECH, Nigeria, 2010) Bello, I.A.; Bello, K.A.; Giwa, A.A.; Owolabi, R.U.; Adebayo, G.B.Nylon-6 fabric was chemically modified with one agent (NH4)2S04 The dyes applied to nylon 6 were synthesized by acetylating the amino group of H-acid and the products, coupled to different diazo coupling components. The percentage exhaustion (%E) of the nylon with each dye were determined spectrophotometrically, using both unmodified fabric and the modified fabric at constant temperature of 95°C .The results show that higher % exhaustion, which is a measure of increase in dye up- take by the fabric, occurred with fabric treated, with (NH4)2S04 while there was no change in the % exhaustion of nylon that was not modified. We gave reason for the profile to be due to hydrolysis. Treatment of the fabric with a condensing agent, dicyandiamide also showed that washing fastness of the treated fabric is higher than that of the untreated fabric.Item Removal of p-Nitrophenol from Aqueous Solution Using Synthesized Silica-Magnetite Composite(2017) Adekola, F.A.; Orimolade, B.O.; Adebayo, G.B.Silica-magnetite composite was synthesized as model adsorbent for the removal of p-nitrophenol (p-NP), a problematic toxicant present in effluents from pharmaceutical and allied industries. The adsorption behavior was studied by batch method. Prepared adsorbent was fully characterized using Fourier Transform Infra-red spectroscopy (FTIR), Scanning Electron Microscopy (SEM), X-Ray Diffraction (XRD) and X-Ray Fluorescence. The optimum conditions of adsorption were determined by investigating the effect of initial p-NP concentration, contact time, adsorbent dose, pH value of aqueous solution and temperature. Adsorption equilibrium time was found to be 60 min. The optimum initial concentration of p-NP was 70 mg/L while the optimum temperature and pH were 30 0C and 2 respectively. The equilibrium adsorption experimental data were fitted best the Langmuir isotherm. The pseudo-second order kinetic model described the adsorption kinetics more effectively. The thermodynamic studies revealed that the adsorption process is spontaneous and feasible. The experimental results have revealed the potential of synthesized material for the removal of p-nitrophenol from aqueous solution.Item STUDY ON PHYSICO-CHEMICAL PARAMETERS OF WATER EFFLUENTS FROM PHARMACEUTICAL INDUSTRIES IN ILORIN, NIGERIA(Faculty of Pure and Applied Sciences, LAUTECH, Nigeria, 2013) Elelu, S.A.; Mciver, F.A.; Adebayo, G.B.; Ahmed, T.S.The present research work deals with the study of some of the important physico- chemical parameter of industrial effluents collected from pharmaceutical in Ilorin, Kwara State. The study reveals that pharmaceutical industries are responsible for polluting the surrounding aquatic environment. It was observed that pH values of effluent samples collected from the pharmaceutical industries were slightly lower than pH of 6.5 to 8.5 as recommended by ISI and WHO. The effluent sample collected shows extremely high Total Dissolve Solid TDS content range of 168-25, 197.42 mg/L and correspondingly high Total Solid (TS) content of 169-16 – 198-63 mg/L. The chloride content in the effluent was 230, 240 and 300 mg/L which were slightly higher than acceptable limit of 200 mg/L set by WHO. The BOD values of effluent sample collected were 1430, 1475 and 1627 mg/L respectively which lie above the maximum permitted BOD content of < 100 to 300 mg/L. The COD values in the different effluents sample were also very much higher than maximum permissible limit of 40 mg/L according to NESREA Standard. The overall result of this study clearly indicated that effluents from these pharmaceutical industries were highly polluted hence, they have resulted in pollution of nearby water body thereby affecting the growth of vegetation and aquatic life. The result of the present investigation point out the need to implement common objectives compatible policies and programme for improvement in the industrial waste water treatment methods.
