Statement of the Problem
The aggressive exploitation of fossil fuels and other natural resources has contaminated the air we breathe, the water we drink, and the land we inhabit. Over a million tons of carbon (iv) oxide 3 and other climatically-important “greenhouse” gases have already been accumulated in the atmosphere (Arpin and Veaweb, 2007). Within the course of a relatively short time, the concentration of carbon (iv) oxide, CO2, has increased by 40%, and now exceed...

Statement of problem
The economic feasibility of processes using activated carbon for treatment of water and waste water is contingent upon re-use of the carbon in multiple adsorptionregeneration cycle. Activated carbon has been used in treating waste water due to its known high adsorptive capacity over various solutes, but after activated carbon has reached its uptake capacity, it must either be disposed off and replaced with fresh carbon or be regenerated. The relative high cost o...

ABSTRACT
This work studied the refining of crude palm kernel oil derived from the kernels within the nut of a palm fruit. This research project was aimed at reducing the non-glycerides present in oil in their crude form using an alkali method of refining. The crude palm kernel oil was first washed with distilled water by heating the mixture in an electric heater for about 2 hours to reduce the impurities present in the oil in their crude form, degummed with phosphoric acid and neutr...

ABSTRACT
The purpose of this work was to study the effect of chemical surface properties of activated carbons for their use in water purification. To achieve this objective, activated carbon in both granular and powdered forms namely: as received and devolatilized carbons were prepared. Proximate analysis of the carbon materials was performed. Mass titration experiments were carried out to determine the point of zero charge of the activated carbon materials. Again, using an ultravio...

SUMMARY
In industry, business, and homes worldwide, metal alloys called stainless steels are used extensively. Stainless steel is a generic term for a large family of iron-based alloys containing a minimum of 10.5% chromium content by weight. The primary alloying element, chromium, forms a thin passive layer of chromium oxide/hydroxide when exposed to air and moisture, which is dense and impervious to water and air, thereby protecting the bulk metal beneath the surface layer. Stainl...

Statement of the Problem
Althoughtremendous research results have been published regarding natural fiber mercerization treatment, which is the primary fiber treatment technique,there are still scanty works conducted in dealing with interaction of factors and optimizing the mercerization treatment conditions. 3 Most parameters considered in mercerization treatment were alkali concentration, fiber soaking temperature and fiber soaking duration. Although similar types of reinforced fib...

Statement of the Problem
Toxic paints still dominate the local market, and as such, these paints are mostly used because they are cheap and readily avaliable. The few available non-toxic paints (washable paint) are sold at high price because the major raw materials are not locally sourced. The behaviours of some of the available washable paints under certain conditions are yet to be established. This research will make use of locally sourced oil to produce and study the behaviour of...

ABSTRACT The uptake of phenol from simulated aqueous solution using agricultural wastes as adsorbents is the focus of this research work. The agricultural wastes used were corn cob and rice husk which were modified with tetraoxophosphate V acid (H3PO4) and carbonized to give corn cob activated carbon (CCAC) and rice husk activated carbon (RHAC) respectively. The surface area of the adsorbents was determined using the Brunauer-Emmett-Teller (BET) nitrogen absorption method. Other physical prop...

ABSTRACT
Mineral ores are usually processed by means of pyrometallurgical or hydrometallurgical processes. Myriad of deficiencies surrounding pyrometallurgical process have spurred research interests geared toward low temperature and lixiviant concentration hydrometallurgical process. Leaching of copper, zinc and iron from Nigerian chalcopyrite, sphalerite and ilmenite ores using binary solutions (HCl-KCl, HCl-KClO3 and HCl-NaNO3) as lixiviants was investigated. The ore samples were...

Statement of the problem
One of the major reasons for food shortage is the unavailability of adequate preservation facilities. Some of the food crops are seasonal, being readily available during some periods of the year and scare during other periods due to inefficient preservation. Potato and cocoyam, though very nutritious, easily deteriorates due to the high moisture content they contain which favors the growth and activities of micro-organisms. Drying is one of the ways of...

Statement of the Problem
The obnoxious state of the Nigerian manufacturing sector has created a dire need for accurate bankruptcy prediction models about the overall outlook of companies. This is precipitated on the overbearing consequences of corporate bankruptcy on key stakeholders. Prior studies have mainly focused on the banking sector, using traditional statistical models, such as discriminant and ratio analysis (Nwidobie, 2017; Egbunike & Ibeanuka, 2015; Ezejiofor, Nzewi,...

ABSTRACT
Perfume extraction refers to the extraction of aromatic compounds from raw materials, using methods such as distillation, solvent extraction, expression or enfleurage. The extracts are either essential oils, absolutes, concretes, or butters, depending on the amount of waxes in the extracted product. Heat, chemical solvents, or exposure to oxygen in the extraction process denature the aromatic compounds, either changing their odour, character or rendering them odourless. In...

It would be difficult to imagine how modern life across the globe would operate in theabsence of synthetic polymers. Although these materials (mostly in the form of plastics) haverevolutionized our daily lives, there are consequences to their use, one of these being their high levelsof flammability. For this reason, research into the development of flame retardant (FR) additives forthese materials is of tremendous importance. However, many of the FRs prepared ar...
