摘要：
The extraction of copper with a liquid surfactant membrane containing LIX 65N as carrier and glutamic acid dioleylester ribitol as surfactant was carried out in a Mixco column. The copper concentration profile along the column was measured. The experimental results were analyzed by the backflow model, taking account of the interfacial reaction between copper in the continuous phase and carrier in the W/O emulsion phase and of the diffusion of copper in the continuous phase without an adjustable parameter. © 1990, The Society of Chemical Engineers, Japan.
