Resumen:
Supported ionic-liquid phases (SILPs), which favorably combine the properties of ionic liquids (ILs) with the advantages of solid supports, were presented in 2009 as an alternative material for solid-phase extraction (SPE). Since then, the number of SILPs used as SPE materials has increased and the results are promising. This report covers various aspects of SILPs: (1)the procedure for their preparation, which clearly depends on the support (based on silica or polymer) where the ILs are immobilized; (2)their interaction mechanisms, which are strongly linked to the SPE protocol and the target analytes; and, (3)their fields of application with a number of selected examples. This is the first review that exclusively describes all SILPs that have been developed to date as sorbents in SPE.
