Abstract
Supported ionic liquid membranes (SILMs) consist of a thin microporous support whose pores are filled with an ionic liquid. The liquid supported membranes have been extensively used for the selective separation of organic compounds and mixed gases during the last decade. The unique properties of ionic liquids such as negligible vapour pressure, greater viscosity and the possibility of minimization of solubility in the surrounding phases by adequate selection of the cation and anion could overcome the instability associated with supported liquid membranes based on organic solvents. Furthermore, it is possible to tailor ionic liquids for specific separation problems by changing the nature of the cation and/or the anion, which opened up new fields of application of supported ionic liquid membranes. In this chapter, an overview is given of methods of preparation and characterization, stability, transport mechanisms and fields of application of supported ionic liquid membranes.
