The preparation of highly pure vanadyl sulfate from sulfate solutions containing impurities of iron and aluminumwas investigated by solvent extraction with 2-ethylhexyl phosphoric acid mono-2-ethylhexyl ester (EHEHPA) and tri-n-butyl phosphate (TBP) as the phase modifier. The extraction and stripping conditions of vanadium (IV) and its separation from iron and aluminum were optimized. Under the...

A number of experimental investigations utilizing different murine species have previously reported: (i) that standard mouse-diets supplemented with physiologically realistic amounts of neurotoxic metal salts substantially induce pro-inflammatory signaling in a number of murine tissues; (ii) that these diet-stimulated changes may contribute to a systemic inflammation (SI), a potential precursor...

The purpose of this study was to evaluate the effect of addition of zinc sulfate to conventional and resinmodified glass ionomer restorative materials. The samples were prepared by addition of zinc sulfate to glass ionomer at different concentrations. The samples were tested for fluoride, zinc and aluminum release at different time intervals. The antibacterial activity of the restorative materi...

The chemical composition and aluminum speciation of sludge incineration residue (SIR) were determined. Cementation of aluminum from sulfuric acid solution using SIR was studied. The results showed that acid-soluble inorganic aluminum was the predominant component in the sludge, and the total leached aluminum increased from 62.2% to 92.9% after incineration. Sulfuric acid dosage and reaction tim...

Two commercially available acidifying litter treatments, aluminum sulfate (alum) and sodium bisulfate, were tested to determine their effects on Campylobacter and Salmonella colonization frequencies and populations associated with broilers raised on treated pine litter. To produce contaminated litter, broiler chicks were inoculated with two bacterial cocktails (multistrain mixtures of campyloba...

Disturbance in water relations is the major causes of vase life reduction and senescence in cut flowers This problem is mainly due to microorganism proliferation in the vase solution which leads to vascular occlusion and reduction in solution uptake by cut flowers. Therefore a comprehensive study was conducted to evaluate the biocidal effect of nano silver particles (NSP) and compare it with so...
