Abstract

Abstract: The interfacial tension was determined with drop method for bis(2-ethylhexyl)phosphoric acid(HDEHP) in different diIuents, such as benzene, toluene, cycl0hexane and n-hexane, and the surface excess was calculated according to the different adsorption isotherms.The extraction kinetics of Ni(Ⅱ) with HDEHPhas been studied and an interfacial reaction mechanism was suggested.The relationship between the interfacial structure and this mechanism was discussed.The interfacial activity of extractant and the effect of diluents give a strong evidence qualitatively for supporting this mechanism.

Key words: Interfacial activity, Diluent, Extraction kinetics, HDEHP
