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; […]

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 […]
Computing the fourth atom-bond connectivity index of the Polycyclic Aromatic Hydrocarbons
Abstract Among topological descriptors topological indices are very important and they have a prominent role in chemistry. One of them is atom-bond connectivity (ABC) index defined as where dv is the degree of vertex v. Recently, a new version of atom-bond connectivity (ABC4) index was introduced by M. Ghorbani et. al. [38] in 2010 and […]
Formulation and evaluation of oral floating In situ gel of Tramadol hydrochloride
Abstract In situ gel forming systems have been widely investigated as vehicles for sustained drug delivery. In situ gel formation occurs due to one or combination of different stimuli like pH change, temperature modulation and solvent exchange. So, In situ gelling system via different route such as oral, nasal, ophthalmic etc can be formulated. In […]
