    (Elsevier, 2019) Nwosu, F.O; Ajala, O.J; Okeola, F.O; Adebayo, S.A; Olanlokun, O.K; Eletta, A.O
    In the recent time, adsorption is a commonly economical way for removal of pollutants from wastewater. Chlorotriazine has been a serious threat to life of both human and animal. Modified kaolinite clays were separately prepared by chemical impregnation method with 2M H2SO4 and 2M NaOH respectively in w/ v of 1:2 for a period of 24h to give unmodified kaolinite (UKC), 2M H2SO4 modified kaolinite (2-AKC) and 2Mm3 NaOH modified kaolinite clays (2-BKC) respectively. The UKC with maximum intake value (125.3mg/g) was derived at equilibrium of 1100mg/L while 96.65mgg−1 of 2-AKC was obtained at equilibrium of 500mgL−1 and that of 2-BKC was found at equilibrium of 700mg/L. The Langmuir isotherm best explained the removal of Chlorotriazine onto various kaolinite clays while pseudo 2nd order kinetics fitted best. Thus, kaolinite clays have been proved as a potential adsorbent for the removal of chlorotriazine molecules

    FISH POND WASTEWATER HYDROPONIC TREATMENT POTENTIAL OF CITRULLUS COLOCYNTHIS
    (Journal of Research in Forestry, Wildlife and Environment, 2019-03) Mokuolu, O.A; Olokoba, S.O; Aremu, S.A; Olanlokun, O.K
    C.colocyn this’ plant hydroponic treatment of fish pond’s wastewater (FPWW) was evaluated. The FPWW was collected from the University of Ilorin aquaculture and tested for the dissolved oxygen (DO), biochemical oxygen demand (BOD), chemical oxygen demand (COD), electrical conductivity (EC), total dissolved solid (TDS), temperature, pH and bacteriological content. The wastewater under treatment was tested for all the physicochemical parameters on weekly interval for the experimental period, while the bacteriological analysis was done before and after the treatment. The values obtained for the physicochemical parameters were statistically analyzed at p<0.05. The physicochemical results observed before application of C.colocynthis treatment technique were 25°C, 540µS/cm, 7.5, 270mg/l, 8.62mg/l, 22.65mg/l and 4.2mg/l for temperature, electrical conductivity, potential hydrogenation, total dissolved solid, 5-day BOD, COD, and the DO respectively. After the fifth week, the analysis of variance of the sample’s results showed that the electrical conductivity, total dissolved solid, 5-day BOD and the COD were insignificantly reduced from 539 to 209µS/cm, from 270 to 102mg/l, 8.62 to 4.8mg/l and from 22.65 to 12.01mg/l respectively at P>0.05. The treatment efficiencies were observed to be 61.29%, 62.22%, 44.31% and 46.97% respectively. Also, the DO increased from 4.2 to 8.12 having percent increment of 93.33%, while the bacteriological analysis showed that FPWW has 215±35 colonies and 2.15±0.35×107 Cfu/ml before the application of C.colocynthis hydroponic treatment and 83±18 colonies and 8.3±0.18× 106 Cfu/ml after hydroponic treatment. The statistical results were insignificant but were within the limits of comparative standards.
