This research investigates the influence of time, pH, and temperature on the adsorption of various metallic soaps onto hematite particles in aqueous suspension. The metallic soaps studied were derived from potassium, calcium, and aluminum cations, combined with shea butter, castor oil, and rubber seed oil. The ultimate goal is to assess their poten...

Derived adsorbates viz; AI3+ , Ca2+ and K± soaps of Butryspermum parkii and those of Hevea brasiliensis oils were prepared. Their uptake onto home-based ore (hematite as adsorbent) was investigated for the role played by spiked ionic charges and at various ionic concentrations. This research supports the fact that the electrostatic and diffusion pr...

Green as one of the primary colours of white light in sunlight is reflected alongside absorption of other wavelengths of electromagnetic radiation by leaf before photosynthesis can take place, with no application of extra external energy and without pollutants. Given that green is one of the primary colours of white light, effect of irradiating H2O...

Light, especially green light in sunlight, is reflected alongside absorption of other wavelengths of electromagnetic radiation by leaf before photosynthesis can take place, with no application of extra external energy and without pollutants. Green being one of the primary colours of white light makes the investigation of effect of irradiation of el...

Introduction: Cardiovascular disease is known to be the leading cause of death globally and it is responsible for one third of all global deaths.The research was conducted to assess some complete blood count, von Willebrand factor, fibrinogen, C reactive protein and ABO blood group that could serve as a biomarker for the diagnosis and management of...

The isomers of C4H5N consisting of eleven members (2-vinyl-2H-azirene, Isocyanocyclopropane, Ally isocyanide, N-vinylethyleneimine, Cyanocyclopropane, 2H-pyrrole, 3H-pyrrole, Ally cyanide, 2-cyanopropene, 2-butenenitrile, Pyrrole) have been studied computationally using the Gaussian-4 (G4) compound model with the Gaussian 09 suite of programs. Quan...

Rapid industrialization has generated large quantities of liquid effluents from heavy metals such as cadmium, cobalt, lead, chromium, nickel, mercury, uranium, selenium, zinc, arsenic, gold, silver, copper and Manganese, etc. The presence of heavy metals such as chromium and cadmium with high level of toxicity detected in surface water has attracte...

Corrosion of X80 steel was investigated in simulated acidizing fluids containing different concentrations of 3-(2-chloro-5,6-dihydrobenzo[b][1]benzazepin-11-yl)-N,N-dimethylpropan-1-amine (3CDA) at different temperatures using weight loss and electrochemical techniques. X80 steel corroded at higher rates in the uninhibited acid solution than in the...

Metallic soap prepared by saponification of melon seed oil (Cucumeropsis mannii N) with copper (II) salt was investigated as corrosion inhibitor for mild steel corrosion in 1 M hydrochloric acid solution. Results reveal that the metallic soap inhibited the corrosion process by spontaneous physical adsorption of the phytochemicals of the seed oil on...

The inhibition of aluminium corrosion in hydrochloric acid solution by ethanol leaf extract of Azadirachta indica was studied by weight loss and thermometric methods. Results obtained show that Azadirachta indica leaf extract leaf extract is a good inhibitor of aluminium corrosion in HCl solution. The inhibition efficiency increased with increase i...

The distribution of aliphatic hydrocarbons and polycyclic aromatic hydrocarbons (PAHs), and their degradability by bacteria in epipelic and benthic sediments from Qua Iboe Estuary mangrove ecosystem and associated creeks were investigated. The research findings revealed that total aliphatic hydrocarbons in sediments ranged from 16.82 mg·kg to 210 m...

Physicochemical properties and fatty acid composition of Poga oleosa oil extracted from its seeds were investigated using standard techniques. The oil was characterized for the following parameters: saponification value (214.58), unsaponifiable matter (8%), iodine value (57.58), acid value (101.54), peroxide value (26.67), ester value (113.04). vis...

Three samples of spent lye from soap manufacturing companies namely Paterson Zochonis Industries (PZ), International Equitable Association (IEA), Kitchen Soap Industries (KSI) all in Aba, Abia State of Nigeria and one laboratory simulated sample (SSL) were analyzed for the amount of glycerol and residual salts. The amount of glycerol in all the sam...

Cellulosic polymers namely cellulose, di-and triacetate were produced from fourteen agricultural wastes; Branch and fiber after oil extraction from oil palm (Elais guineensis), raffia, piassava, bamboo pulp, bamboo bark from raphia palm (Raphia hookeri), stem and cob of maize plant (Zea mays), fruit fiber from coconut fruit (Cocos nucifera), sawdus...
