摘要： 本文以苯为稀释剂,考察了2-乙基己基膦酸单2-乙基己基酯(HEll(EHP),P507从硫酸盐溶液中萃取Zn(Ⅱ)的动力学过程。

Abstract: Kinetics of Zinc(II ) extraction from aqueous sulfate solution with HEH[EHP] in benzene has been studied by means of the classical polarography. The effects of the stirring-speed, interfacial area between two phases, and the concentrations of Zn2+, H+ , SO42- and HEH[EHP] on the extraction rate for the titled, system have been investigated. The results indicate that extraction process is controlled by the interfacial reaction when the stirring-speed is over 200 rpm.
