摘　　要：以ＨＥＨ［ＥＨＰ］（Ｐ５０７）为流动载体，探讨了Ｃｕ（Ⅱ）的传输行为，考察了内、外相酸度、膜相载体浓度、温度等因素对传质速率的影响．结果表明，两界面处的萃取反应、离子的扩散速度及膜相的微细结构共同影响着离子的传质速率．并对该体系富集、传输Ｃｕ（Ⅱ）的适宜条件进行了讨论．The transport behaviours of copper (Ⅱ) through emulsion liquid membrane by using HEH(EHP) as a carrier have been investigated. The influence of various factors on the rate of transport was stuided. The proper conditons of the transport of copper(Ⅱ) through emulsion liquid membrane process were obtained.
