Importance of Mn(III) Availability on the Rate of Cr(III) Oxidation on δ-MnO2

The oxidation of Cr(III) to Cr(VI) significantly increases its mobility and toxicity and therefore its environmental hazard. The oxidation rate of aqueous Cr(III) in a suspension of δ-MnO2 (birnessite) was investigated at different pyrophosphate concentrations and pH values. Pyrophosphate, which is...
