Layered, poorly-crystalline Mn(IV)O2 phases are abundant in the environment. These mineral phases may rapidly oxidize Cr(III) to more mobile and toxic Cr(VI) in soils. There is still, however, little knowledge of how Cr(III) oxidation by Mn(IV)O2 proceeds at the microscopic and molecular levels. Therefore, the sorption mechanisms of Cr(III) and ...
