Synthesis, Optimization and Characterization of Silica from Sugar Cane Bagasse and Rice Husk

Adamu M., Tsado D.G. & Umar S.

Silica was synthesized from Sugar cane bagasse and rice husk (Agricultural wastes). The pretreated samples were ashed and reacted with sodium hydroxide to produce sodium silicate from which silica was precipitated using Tetraoxosulphate (VI) acid. The optimum yield of silica from sugar cane bagasse was obtained at ashing temperature of 700 OC,....

Comparison of Diffusion and Spectrophotometric Methods for in Vitro Antibacterial Evaluation of Extract of Ficus capensis Bacteria

Musa A.D.

As part of an ongoing study to provide pharamacological basis for the application of Ficus capensis in Igala traditional medicine for the treatment of several febrile illnesses and infective disorders, the antibacterial activity of the plant extract was investigated at low concentrations using diffusion and spectrophotometric methods. This was aimed at determining the sensitivity of the methods at low concentrations...

Synthesis, Antibacterial and Antifungal Activities of Some Transition Metal (II) Chelates Derived from Benzoyl Acid Hydrazide

Salawu, O.W.

The reaction of benzoylacetylhydrazine with hydrazinemonohydrate gave the hydrazide derivative. The hydrazide reacted with some transition metal (II) ions to give chelated complexes. These complexes were characterized by elemental analysis, FT-IR and molar conductance...
