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...
ABSTRACT Cassava is considered as a potential source for the commercial production of bioethanol because of its availability and low market price. It can be used as a basic source to support large-scale biological production of bioethanol using microbial amylases. With the progression and advancement in enzymology, starch liquefying and saccharifying enzymes are preferred for the conversion of complex starch polymer into various valuable met...
This study covers the evaluation of the synergistic effect of Datura stramonium leaves extract-Zn2+ in the corrosion inhibition of mild steel in well water. Varying effects of different concentrations of the extract and 5ppm of Zn2+ on the corrosion inhibition of the mild steel specimen will be determined in order to ascertain the synergistic effect that exists between the leaf extract and Zn2+
ABSTRACT The kinetics and optimization of inhibitive action of leaves extract of pawpaw, Azadirachta indica (neem tree) and bitter leaf on corrosion of mild steel in acidic medium was studied by weight loss technique using central composite design of response surface methodology for optimization. The metal was analyzed using Atomic Absorption Spectrophotometer to determine its elemental compositions. The extract was obtained by liquid extraction using ethanol and was analyzed to determine ...
ABSTRACT Nowadays, the destruction and pollution of humane environment has produced an ever growing awareness worldwide of the need for more effective sedimentation processes. The main aim of this project was to design and fabricate an experimental sedimentation rig with the objective to determine the rate of settling against time using calcium carbonate as a test sample.The rig consists mainly of the cylindrical tank, valves, motor, stirrer, and the sight glass. For the test run, 82 litres o...

Nickel doped zinc oxide (Ni/ZnO) nanostructures have the potential to improve the performance of electrochemical capacitors. This study investigates the preparation of Ni/ZnO nanomaterials by facile co-precipitation (CPM) and hydrothermal (HTM) methods. The effect of the synthesis methods on the optical, structural, chemical and morphological properties on ZnO products is investigated using ultra violet (UV)-visible spectroscopy, X-ray diffraction (XRD), field emission scanning electron micro...
ABSTRACT The objective of the work is the catalytic conversion of waste plastics into fuel oil and solid wax using Ca(OH)2 and the design of pyrolysis reactor. Plastic wastes such as, polypropylene, low density polyethylene, high density polyethylene, polystyrene are the most frequently used in everyday activities and disposed of to the environment after service. There are a number of methods by which plastic wastes can be managed such as incineration, recycling, land filling, thermal and cat...
Abstract Due to the toxic effects of chemical pesticide and other agro chemicals on human beings and livestock, residual toxicity, environmental problems, pest out-breaks and drastic effects on beneficial insects the use chemical pesticide and other agro chemicals are getting reduced /being banned globally. But Biopesticides that are extracted, for example, from neem seed can tackle these problems to make it more eco-friendly, economically viable and socially acceptable for the farmers. Bio...

The spread of pollutant in an area is partly a function of wood burning in local kitchens by the population of the area. This pollution generated through combustion of wood fuels presents difficult environmental challenges to societies as it could degrade the environment and affect human health and quality of life. Wood burning emissions are major contributors to air pollution in rural areas as they contain harmful gases. The level of carbon monoxide in the air in two location in oleh town ...
ABSTRACT The adsorptive removal of the colour pigment (due to high content of carotenoids) from palm oil using ortho-phosphoric acid activated kaolin clay was investigated in this research. The clay was activated at different acid concentrations to improve its adsorptive capacity. In order to study the effect of process variables on the bleaching efficiency of the raw and activated clay ...
ABSTRACT The presence of methylene blue (MB) in wastewater is a major concern in the environment due to its low biodegrability and harmful effect on man. The treatment of effluent containing such dye is important where adsorption on activated carbon (AC) produced from agricultural waste is of great choice. Optimization of the removal efficiency of MB from aqueous solution onto AC prepared from mango shell was investigated. The AC was prepared from mango shell, activated with BaCl2 at I.R (0.0...
ABSTRACT This study was conducted to remove mango shell waste which is one of the seasonal environmental nuisance items and recycle it as a precursor for the production of activated carbon. Discarded mango shells were sourced from local vicinity, and they were washed thoroughly to remove dirt, sundried and reduced to smaller sizes. Two-Level Factorial Design under Factorial Methodology of Design Expect (10.0.1) software was employed to optimize interaction of impregnation ratio (0.033 - 0.167...
ABSTRACT This research work show cases the potentials of Itakpe Iron concentrate for Magneto-rhelogical abilities. The concentrate was first ball milled to size reduce it then subjected to low magnetic strength from magnetic bits in-situ the magnetic fluid. It was determined that temperature affected the fluid inversely, as temperature increased at the shear rates from the viscometer and Newtonian viscosity calculated reduced, giving a negative relationship between temperature and Newtonian v...
