【 摘 要 】

References(7)Cited-By(6)The rate of iron(III) extraction and stripping by TO A in benzene-hydrochloric acid aqueous solution system is elucidated. Interfacial reaction between iron in neutral form in the aqueous phase and the adsorbed amine-acid complex plays a significant role in the extraction and the stripping rates when the hydrochloric acid concentration is low in the aqueous phase. At high acid concentration, the rates are controlled by the diffusional steps in the aqueous and the organic phases.
