    Abstract: Oxidation kinetics of L-citrulline (Cit) by hexachloroplatinate(IV) (HCP) was studied spectrophotometrically in perchloric acid solutions in the presence of ruthenium(III) catalyst at a constant ionic strength of 1.8 mol dm-3 and at 20°C. The reaction rate was very slow in the absence of the catalyst. The reaction showed first order kinetics in bot... Show More

    Abstract: A novel oil highly absorptive resin was prepared by a suspension polymerization using 1-butyl -3- (2- methacryl) ethyl imidazolium hexafluorophosphate (BMIm)PF6-, methyl methacrylate (MMA), and butylacrylate (BA) as monomers, azobisisobutyronitrile as initiator, N, N methylenebis (acryl amide) (MBA) as crosslinking agent and polyvinyl alcohol (PVA)...
