Abstract: Kinetics of the extraction of chromium(Ⅲ)with HEH(EHP) in kerosene solution from aqueous sulfate solution has been studied. To interpret the experimental results of the influence of the concentration of chromium(Ⅲ),extractant,hydrogen ion and sulfate radical on the rate of extraction, a mechanism for the extraction is proposed For Cr(Ⅲ)exists in various forms in aqueous solution [Cr(Ⅲ)]total=[Cr+3]+[Cr(OH)2+]+[Cr(OH)2+]+[CrSO4+]the rate of the extraction can be expressed as follows
