Ionic Liquids and Polymeric Ionic Liquids in Analytical Environmental Applications

Abstract

Ionic liquids (ILs) are a class of organic salts with unique properties and have been shown to be particularly useful for the development and improvement of sample preparation and detection methodologies. ILs and polymeric ionic liquids (PILs) have played an important role in the analysis of environmental samples. These compounds have been widely applied in various microextraction techniques due to their tunable analyte selectivity, low volatility, good thermal stability, as well as variable viscosity and solvent miscibility. The unique properties also make ILs and PILs an emerging class of stationary phases in gas chromatography (GC). IL/PIL-based stationary phases exhibit excellent applicability in multidimensional GC separations. This chapter will highlight the applications of ILs and PILs in a number of microextraction techniques in addition to their utilization in separation science with a particular emphasis on their use in environmental analysis.
