A diffusion-reaction model for Type I facilitated transport in the liquid surfactant membranes has been developed. The mass transfer redistances both inside and outside the emulsion globules and the reaction between the diffusing component and the internal reagent are taken into account simultaneously and the perturbation solutions for the non-linear equations have been obtained. Predicted results from the model show that the solutions are convergent; the extraction rate increases with increasing in E, Bi (Biot Module) and Da (Damkohler Module),.respectivety. From this model, one can estimate whether the process is controlled by diffusion or by reaction. The model predictions are in good agreement with the experimental data on the extraction of acetic acid. In general, the zero-order solution is adequate to describe the extraction process in the liquid surfactant membranes.
