Appraisal of heavy metal contents in soils using different digestion methods

Abstract The concentration of some heavy metals (Fe, Cu, Zn, Cr, Pb, Ni, Cd) were analysed in soils in and around Keteren-Gwari Mechanic village, Minna metropolis, Niger State, North-central Nigeria using Atomic Absorption Spectroscopy (AAS) (Buck Scientific 210VGB). Two digestion methods were used to concentrate the metals. Mean concentration for Fe was 6548±72.94µg/g; 24.57±16.74µg/g Cu; […]

Formulation of Colon Specific Didanosine Enteric Coated Matrix Tablets Using pH Sensitive Polymer

Abstract The objective of present study is to develop the colon specific Didanosine enteric coated matrix tablets using release retardant polymer and pH sensitive polymer Eudragit L100 that retard the liberation of drug in upper gastro intestinal system and also show progressive release in colon. The influence of core tablet compositions, polymer combination ratios and […]

Abstract In the past decades, crop diseases and human health is always at stake and the emerging problem on the use of synthetic antipathogens and medicine is one of the most difficult to combat.  This current research was carried out to determine the phytochemical constituents and the inhibitory activities of Samanea saman (Jacq.) Merr. pods. […]

Synthesis and Antimicrobial Studies of 3-(3-Hydroxy-4-Methoxyphenyl)-1-Phenylprop-2-en-1-One

Abstract This paper reports on the synthesis of 3-(3-hydroxy-4-methoxyphenyl)-1-phenylprop-2-en-1-one by Claisen-Schmidt condensation of acetophenone with an aromatic aldehyde (vanillin) in the presence of aqueous solution of 60% sodium hydroxide at room temperature. The percentage yield of 3-(3-hydroxy-4-methoxyphenyl)-1-phenylprop-2-en-1-one was found to be 32.3% after recrystallization from ethanol. The synthesized 3-(3-hydroxy-4-methoxyphenyl)-1-phenylprop-2-en-1-one was characterized using Fourier Transform Infrared […]

Antimalarial Activity of 3-(4-Nitrophenyl)-1-Phenylprop-2-en-1-one and Its Metal Complexes

Abstract Antimalarial resistance is currently the greatest challenge to the effective treatment of malaria globally. In this work, 3-(4-nitrophenyl)-1-phenylprop-2-ene-1-one, as well as the Fe(III), Ni(II) and Mn(II) complexes of 3-(4-nitrophenyl)-1-phenylprop-2-ene-1-one were synthesized and characterized using Fourier Transform Infrared (FTIR) Spectroscopy, Thin Layer Chromatography (TLC) and melting point analysis. The obtained yields of the Fe(III), Ni(II) […]

Extraction of Uranium from the Raffinate of Egyptian Phosphoric Acid Purification Using Aliquat336 Extractant in One Step

Abstract This paper describes the extraction of uranium from raffinate phosphoric acid purified using aliquatR336 in kerosene as a selective extracting agent of uranium, Several factors were studied for the maximum extraction of uranium. mainly aliquatR336 concentration, shaking time, aqueous/organic phase ratio, the diluents effect and temperature on the extraction, Effect of different stripping agents […]

Bioremediation of Crude Oil Polluted Soil: Maize Husk Compost as a Test Bioremediant

Abstract Crude oil simulated soil was treated with 300g, 450g and 600g concentrations variation of maize husk compost (MHC). The effects of maize husk compost (MHC) treatment on physicochemical properties of crude oil contaminated soil, total petroleum hydrocarbon (TPH) %, biostimulation efficiency (B. E) % were studied. The results indicated that the composting process greatly […]
