ABSTRACT
The emulsion liquid membrane (ELM) concept constitutes an elegant way of interposing an extensive yet extremely thin membrane between two liquid phases without any mechanical appurtenances. Its basic simplicity allows easy regenera tion, freeing the user of many of the potential problems inherent in conventional membrane processes. However, since the membrane is a liquid, ELM does not permit pressure-driven separations and is thus restricted to concentration-driven permeation processes.
