    AIR POLLUTION STUDIES. II: MONITORING OF SULPHUR (IV) OXIDE EMISSION BY MOTOR VEHICLES AT A BUSY ROUND-ABOUT IN ILORIN.
    (Faculty of Science, University of Ilorin, 1998) Lawani, S. A.; Adebayo, G. B.
    Sulphur (IV) Oxide concentrations at a busy round-about in the city of 1I0rin versus lime of day were measured on 4 different days staggered throughout the month for 12 months 0+ the year. The results showed that the highest peaks occurred at 8-9a and 3-4p.m. each day. These two time periods corresponded to the busy hours when workers were going to their offices and returning home respectively. Comparison of the values obtained at the round-about with those at a remote rural area suggests that the relatively high SO2concentration at the round-about came from motor vehicles. While the measured SO2 levels are within the range that is tolerable for human beings, the low levels obtained might be harmful to children, the elderly and people with chronic respiratory problems.

    Conversion of Jatropha curcas oil to biodiesel using potash from cocoa pod husk (CPH) and palm kernel frond (PKF) as catalyst
    (Faculty of Science, University of Ilorin, Ilorin, 2014-09-01) Ameen, Mubarak; Adekola, F. A.; Adebayo, G. B.; Adekola, O. F.; Belewu, M. A.; Rahman, S. G.
    Caustic potash extracted from the ashed samples of cocoa pod (Theobroma cacao) and palm kernel fronds (Elaeis guineensis) was used to catalyse the conversion of Jatropha curcas oil to biodiesel. The physicochemical parameters and fatty acid components of the prepared biodiesel were comparable to those of the biodiesel prepared with commercial KOH. This work, thus established the fact that it is possible to use erstwhile wasteful plant products for useful purposes

    The Nigerian Journal of Pure and Applied Sciences
    (Faculty of Physical Sciences and Faculty of Life Sciences, Univ. of Ilorin, Nigeria, 2016-10-01) Okeola, F. O.; Amoloye, M. A.; Adebayo, G. B.; AbU, T. O.; Ameen, O. M.; Obiechina, B.
    Physicochemical analysis of crude oil and petroleum products were carried out on two different samples of crude oil and eight different samples of petroleum products. The parameters tested were specific gravity, API determination, aniline point, kinematic viscosity, water content, distillation profile, flashpoint, pour point and metal content determination. The tests were carried out using standard procedure of American society for testing and materials (ASTM). The result shows that the crude oils were different in terms of API gravity and specific gravity.API gravity of 36.2 and 31.5 respectively for crude oil C1 and C2 shows that they are not heavy crude oil. The low water content and low viscosity of the crude oils lower the risk of pipe and container corrosion and flow difficult. API gravity of gasoline and kerosene was more than 30, while that of engine oil and diesel oil was more than 30.For petroleum products, the result of density, specific gravity, viscosity and kinematic viscosity shows the value of those parameters increase from light fraction to heavy fraction. The pour point and flash point recorded for light fractions was lowered than that of heavy fractions, for both samples of gasoline P1 and P2, flash point is 49.3 oF and 51.1oF while pour point is -3 oC and -5 oC respectively, for Diesel oil D1 and D2 flash point is 244.2 and 240.2 oF and pour point is +3.2 and +3.0 oC respectively. The distillation profile result of both samples of gasoline, showed the temperatures to be in normal range. The level of heavy metal analysed were generally low but metal such as iron, copper, zinc were in abundance in the samples of the crude oil and petroleum products. The results are discussed in terms of importance and implication.

    SPECTOPHOTOMETRIC DETERMINATION OF Cu, Ni, AND Fe IN TWO ENVIRONEMNTAL SAMPLES USING PARA-PHENYLENEDIAMINE EXTRACTED FROM A NATURAL MINERAL DYE
    (Department of Chemistry, University of Ilorin Ilorin, 2011) Adebayo, G. B.; Adekola, F.A.; Olagunju, O.T.
    A simple, sensitive and novel spectrophotometric method has been developed for the determination of trace elements (Cu, Ni and Fe) using para-phenylenediamine extracted from a mineral dye with diethyl ether. The method was applied to the determination of these metals in algae and cattle manure samples obtained from a polluted river and cattle house within Ilorin Metropolis. The concentration of the metals in algae sample were 30.15±4.1 51.9±9.4 and 1055.25±8.8 ppm for Cu, Ni, and Fe respectively while cattle manure were found to be 15.5±2.1, 25.15±5.5 and 429.15±17.2, ppm for Cu, Ni and Fe, respectively. Two standard methods of determination of heavy metals, AAS and XRF were also used to determine the same metals in the environmental samples. The results obtained were found to be of no significant difference (p ‹ 0.05) from the result of developed method.
