Membrane separation still continues to be one of the major challenges not only in chemical and biotechnological production processes, but also in waste water treatment. The major problem associated with solute recovery by membrane processes is the restrictive compromise between selectivity and flux: High solute selectivity involves the use of conditions that lead to relatively low mass fluxes in the membrane. Supported ionic liquid membranes offer a range of possible advantages: 1. Molecular permeation is much higher in liquids than in polymers, as liquids allow higher fluxes; 2. The selectivity of the separation can be influenced by variation of the liquid - especially ILs offer the advantage of a wide variety of properties; 3. Thanks to their special mixing behaviour ILs as liquid membranes easily allow three-phase systems; 4. Contrary to the extraction, only small amount of liquid is necessary to form the liquid membrane, thus allowing also the use of more expensive materials. Practical examples of utilization of ILs in downstream processes are given. Acknowledgements The Ministry of Education, Youth and Sports project no. LH14006 is acknowledged for financial support.
