The extraction of copper ion was carried out using liquid surfactant membranes containing LIX65N as a mobile carrier.
A mathematical model for the extraction was proposed. In this model, W/O/W emulsion consists of a large number of oil drops containing smaller, but more numerous water droplets. The calculated results agreed with the experimental ones, and the effects of concentration of various component on the extraction rate were clarified. The overall extractionrate was controlled by both the reaction at external water-oil interfaces and the diffusion of the mobile carrier within the oil phase.
The extraction rate could be also evaluated by a simple model in which the liquid membrane consists of a single layer, considering the effective thickness of liquid membrane.
