Abstract
Supported liquid membranes preserve the selectivity and fast diffusion characterizing the solvent. At the same time they impart compact transfer from one aqueous phase to the other, sacrificing the mechanical and chemical stability of normal polymeric membranes. The liquid membranes comprising double emulsion are one step closer to conventional extraction and require a step analogous to stripping. To take advantage of the small volume of solvent, highly specific and effective extraction agent like crown-ethers are currently introduced. In hydrometallurgic separation synergistic extractants are often effective. For incorporation into liquid membranes, bifunctional extractants incorporating the elements of the synergistic structure must be developed.
