Oxidation of soils with 333 mM potassium permanganate (KMnO4) has been identified as a means to quantify labile soil carbon (C) and may have potential for rapid measurement of biologically active soil C. In the current study, active C pools in several soils were estimated by oxidation with a range of KMnO4 concentrations and compared to estimates determined from carbon dioxide evolution during ...

Potassium permanganate (KMnO4 ) is a powerful oxidising agent. In its raw form, it an odourless, sweet-tasting, dark-purple substance, available in ready-to-use solutions, pellets, tablets, crystals and powder form. clinical practice historically, has been used as antiseptic antifungal rural South African communities, however, KMnO4 many traditional uses, including use snake repellent, treatmen...

A method for the determination of selenium by ion chromatography (IC) after oxygen flask combustion has been developed and applied to the determination of selenium in bulk prednisolone. We found elemental selenium [Se(0)], selenite ion [Se(IV)] and selenate ion [Se(VI)] (ca. 5, 75 and 20%) in the absorbing liquid obtained by oxygen flask combustion of Se(0), Se(IV) and Se(VI). Se(VI) was direct...
