Ionic liquid based aqueous biphasic systems (ABS) have emerged in the last few years as promising media for application in extraction and separation processes. Being based on hydrophilic ionic liquids they provide a much broader range of phase polarities and lower phase viscosities than conventional polymer based ABS allowing for a faster mass transfer and easier fluid handling.
In our research group we have been studying the impact on ABS formation ability of the ionic liquid cation and anion type. Organic and inorganic salts, in a wide range of pH have been used as ABS inducing compounds and the ability of these systems to purify a range of neutral or charged biomolecules has been investigated. Results of five years of research, including a great deal of recent results, on the interactions between salts and ionic liquids in aqueous solution, their effect upon the formation of ABS, and the potential of these systems for extraction purposes will be addressed.
