A microscopic and spectroscopic study of rapid antimonite sequestration by a poorly crystalline phyllomanganate: differences from passivated arsenite oxidation

Abstract

Surface passivation during the adsorption of Mn(ii) and the formation of Mn(iii) was the predominant cause for the decrease in the As(iii) oxidation rate, whereas it may not have been the limiting factor during Sb(iii) oxidation.
