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

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.
