ABSTRACT A study on hydrogeochemistry and quality of shallow water and engineering properties of soil around the Adeta area in Ilorin was carried out based on data obtained from the field and laboratory. Groundwater flow, descriptive, and multivariant statistical analyses, piper, stiff and durov diagrams, as well water quality indices were used to describe hydrochemistry and water quality suitability of the area. Grain-size distribution, Atterberg limit and permeability indices were used to d...
ABSTRACT The physical properties of CNSL extracted by pyrolysis was studied using standard procedures. The physical properties of the CNSL studied and results obtained compared with other extraction methods (hexane extracted and decarboxylated) from literature are moisture content 4.1%, (6.40%, 3.2%), specific gravity 0.943 (0.926, 0.926) viscosity 57cp (40cp, 358cp), pH 4.5 (4.5, 5.2) and the percent composition of the CNSL compared with those from literature are cardol 27% (30%, 31% (carda...
ABSTRACT The investigation of nitrate adsorption onto Brachystegia spiciformis leaf powder from waste waters was performed. Characterization for the functional groups of the biomass before and after nitrate sorption as well as after desorption was done using an FTIR spectrophotometer. The effect of pH, contact time, dosage and initial nitrate concentration was investigated. The Brachystegia spiciformis leaf powder had amine, carboxylic and hydroxyl groups that were involved in nitrate remova...
ABSTRACT The project research entailed the production of high quality sealant incorporating a local raw material for sealing holes and gaps in various materials like metal and plastic. Two samples of acrylic sealants were produced, the first samples which is the standard formulations involved the use of silica gel as a major adhesion promoter and the second samples which is the research formulations involved the use of sand (sharp colourless sand with 59% silica/silicondioxide composition)) a...
ABSTRACT Pausinystalia yohmibe is a member of thefamilyRubiaceae. It is a valuable medicinal tree, distributed in evergreen closed canopy forests in West Africa. It is traditionally used for treatment mostly on erectile dysfunction. This research was carried out to evaluate the immunomodulatory effect of (Pausinystalia yohmibe) stem bark methanolic extract. The yohimbe extract has been reported for its medicinal use for the treatment of impotence in men and for its anti-oxidants effects bu...
The effects of temperature, dielectric constant and catalysis in the kinetics of the oxidation –reduction reactions (involving electron transfer) of N-(2-hydroxy-ethyl) ethylenediammine- N’,N’,N’-Triacetatocobalt (II) by Cu2+ cation were determined. The dielectric constant was decreased from 63.05 to 43.18 and it was found that the rates of the reaction did not show any appreciable change. This seems to mean that the change in the dielectric constant of the medium had no effect on ...

Abstract: The purpose of this study is the preparation of activated carbon using a suitable industrial sludge. The characterization of two types of industrial sludges showed that paper sludge was a better option over rice husk. The activated carbon produced from pyrolysis of paper mill sludge was chemically activated with various activating agents like zinc chloride, potassium hydroxide and potassium chloride. A systematic investigation of the effect of impregnation ratio, activation temp...
Azeotropic distillation of ethanol-water mixture is accomplished by adding a volatile third component to the liquid which changes the volatility of one of the two components more than the other so the components are separated by distillation. The two components to be separated often have similar boiling point components which do or do not azeotrope in the binary mixture, but sometimes there are components which do azeotrope despite having vastly different boiling points. It is likely that in ...
This project study was aimed at designing, fabricating, and evaluating the performance of a double effect evaporator, which was used to evaporate sugar syrup to be used for students’ demonstration. During the course of the study, the methods that were used comprised of the material balances, energy balances, and determination of the component parts of the evaporator. The results from the study included the overall material in the evaporator’s system, the material balance for each effect, ...
ABSTRACT Oil obtained from orange peels and velvet tamarind nut by solvent extraction (n-hexane and acetone) using the soxhlet extractor were investigated as feedstock’s to determine some of the suitable parameters such as iodine value, saponification value, specific gravity, density, acid value and free fatty acid value, and their percentage yield that are suitable for biodiesel production. The density of orange and tamarind oil were found to be 0.9326g/cm3 and 0.8541g/cm3 respectively, th...
EXECUTIVE SUMMARY This work presents the design of a plant that will produce 250000kg/yr of lindane from benzene, chlorine and water at high temperature and pressure using direct chlorination method. The feeds are sent into a chlorinator, the crude product from the chlorinator is continuously decanted into a decanter and the bottom product HCl i...
ABSTRACT The need for effective and efficient means of oil extraction has been a concern in recent time. Hence, this study aimed at the oil extraction from Moringa oleifera seeds using the Microwave-Assisted extraction method. The extraction process was modeled using Response Surface Methodology (RSM). Also, the evaluation of Moringa oleifera oil as a good feedstock for biodiesel production was carried out. Oil was extracted from the M. oleifera seed kernel using Microwave-Assisted meth...
