Abstract
Mathematical models describing the mass transfer through facilitated liquid membranes are proposed and solved analytically. A self-adjoint operator method is applied to solve the coupled differential equations with discontinuity in the boundary conditions. It is assumed that equilibrium of the solute at the interfaces is maintained during the separation process. The effects of film resistance are studied/ and a first order kinetic model is used to simulate the reaction which takes place at the membrane-internal phase interface.
Experimental results indicate that the model with external film resistance consideration is in good agreement with the experimental data. This shows that most of the resistance of mass transfer across liquid membranes lies on the interface between source phase and emulsion globules.
The effects of several factors on the separation process such as pH values, carrier concentration, treatment ratio and reacting reagent concentration are investigated. Selectivity analysis of the extraction of copper and lead is also presented to show the selective characteristic of facilitated liquid membrane systems.
