Oxidation of manganese sulfate to manganese dioxide in 30% sulfuric acid

The electrochem. oxidn. of Mn(II) in H2SO4 (30% wt.) has been studied using cyclic voltammetry. The mechanism was shown to be of the type ECE (Electrochem.-Chem.-Electrochem.). The deposition of MnO2 on the anode can be avoided by inhibiting the chem. reaction step, either by slowing it or by minimizing the mean residence time of Mn(III) ions near this electrode.
