Oxidation of antimony (III) by amorphous iron and manganese oxyhydroxides [PDF]

Chemical Geology, 2001
Abstract Amorphous forms of natural and synthetic Fe oxyhydroxides and synthetic Mn oxyhydroxides were used to study the oxidation of antimonite, Sb(III), at different pH values. Sb species were measured by differential pulse adsorptive stripping voltametry (DPACSV).
