Abstract Sodium diethyldithiocarbamate is found in trihydrate form (SDDCT) as fine yellowish-white solid crystals. SDDCT is a chelating agent that primarily used in the analytical determination of copper, nickel and many other metals. It has been identified as metabolite of disulfiram, whose primary role is in the treatment of chronic arsenic poisoning. The toxicity of […]
Composition of the essential oils of two Umbelliferae herbs (Ferula communis subsp. communis and Smyrnium cordifolium) growing wild in Turkey
Abstract In this study, the essential oil composition of Ferula communis L. subsp. communis and Smyrnium cordifolium collectedfrom Turkey were studied. The qualitative and quantitative essential oil composition were determined and compared with each other. The chemical composition of the essential oils obtained by hydrodistillation from Ferula communis subsp. communis and Smyrnium cordifolium were investigated […]
Comparative Studies of Polycyclic Aromatic Hydrocarbons in Raw and Charcoal Roasted Beef Consumed Within Port Harcourt City and Environs
Abstract Analysis of raw and roasted beef (suya), sold and consumed in Iwofe, Trans Amadi and Port Harcourt city were screened for the presence of 16 polycyclic aromatic hydrocarbons (PAHs). Column chromatography, packed with anhydrous Na2SO4 and silica gel were used for PAH extraction with dichloromethane as the eluting solvent. The identification and concentration of […]
Phytochemical and Elemental Determination of Balanites aegyptiaca Leaves and Stem bark in Hong Local Government Area of Adamawa State, Nigeria
Abstract The leaves and stem bark of Balanites aegyptiaca are popularly consumed as vegetables or herbs in Adamawa state of Nigeria. In view of its importance in Hong local government area, the leaves and stem bark were collected from 10 locations for elemental and phytochemical determination. Atomic absorption spectrophotometer (AAS) was employed for the elemental […]
Adsorption of Reactive Blue19 from Aqueous Environment on Magnesiumoxide Nanoparticles: Kinetic, Isotherm and Thermodynamic Studies
Abstract Water pollution due to discharge of dye containing effluents is one of the environmental problems of serious concern today. The main purpose of study is to investigate the efficiency of magnesium oxide nanoparticles (MgO-NPs) on the removal of Reactive blue 19(RB19) from its aqueous solution. The influence of various process parameters such as pH […]
Fullerene C60 for Tyrosol Retaining
Abstract The main aim of this work is to determinate the adsorption of tyrosol on fullerene C60. By varying the amount of carbon fullerene C60 and maintaining tyrosol solution concentration constant, the adsorption percentage was evaluated. Detailed analysis on the adsorption isotherms were accomplished successfully. Four isotherms which are Freundlich, Langmuir, Sips and Redlich-Peterson were […]

Abstract Parquetina nigrescens belonging to the Periplocaceae family is a plant reported to have diverse medicinal uses, this study was aimed at determining the chemical composition, antioxidant activity and cytotoxicity of the essential oils of the leaves and stems of the plant. The chemical composition of the essential oils determined using the Gas Chromatography-Mass Spectrometry […]
Refinement in Obesity Model Induced by Fructose with Intragastric Administration
Abstract Obesity is defined as the accumulation of adipose tissue, overweight and obesity are defined on the basis of body mass index and this is accompanied by an increased prevalence of comorbidities as type 2 diabetes, cardiovascular and metabolic disease in the population. The research related to obesity, overweight and metabolic syndrome use animal models, […]
A Study on Acid – Base Indicator Property of Flowers of Impatiens Balsamina
Abstract Indicators are used to determine the equivalence point in acid – base titrations (neutralization titrations). They exhibit sharp color change with respect to change in pH. Popularly used indicators for neutralization titrations are synthetic chemicals. They are found to have hazardous effects in human body. The highly colored pigments obtained from plants are found […]
Spectrophotometric Determination of Charge Transfer Complexation between Cimetidine and Chloranilic Acid
Abstract A simple and sensitive spectrophotometric method is described for the assay of cimetidine. Modern analytical technique for cimetidine in various dosage forms are limited by cost and absence of high technological equipment especially in the third World countries including Nigeria. The research investigates the use of charge transfer complexation in the spectrophotometric assay of […]
