Metal ions diffused from the feed compartment to the stripping compartment through an hybrid Donnan dialysis which consists to combine two ion exchange membranes with solvent impregnated resin (SIR). The aim of this work is to study the recovery of Pb(II), Ag(I) and Cu(II) from nitrate solutions by using SIR combined with classical Donnan dialysis. The resin has been prepared by impregnating the Amberlite XAD-4 using three different extractants namely: di-2-ethyl hexyl phosphine acide (D2EHPA), tris-octyl phosphine oxide (TOPO) and Diphenylthiourea (DPT).

Ion exchange and sorption have found widespread use in the recovery, separation and purification of metals; the most notable advances have occurred with uranium, precious metals and the platinum group metals. Separation processes based on sorption are not energy intensive and can be applied to low grade mineral resources and to by-product recovery of valuable metals. In this respect, the process technology is similar to solvent extraction which has been so successfully applied to the recovery and purification of base metals such as copper.

Ion exchange is a process in which cations (anions) in a liquid are exchanged for cations (anions) on a solid sorbent, maintaining electroneutrality in both phases. Ion-exchange resins consist of synthetic organic polymeric materials generally categorized according to functionality as either strong or weak acids or bases. Experiments have shown that the sorption of uranium from acidic sulphate solutions onto strong base anion exchange resins is particle diffusion controlled in the uranium concentration range . 001–0. A simplified diffusion model, based on Fick's Law, fits the kinetic data at each concentration.
