As a class of green organic compounds,ionic liquids have some excellent properties,such as negligible vapor pressure,good solubility and thermal stability,high ionic conductivity and wide electrochemical stability window.Therefore,they have been widely applied in the fields of chemistry and chemical engineering,and nowadays have gained more and more attention.This paper reviewed the recent applications of ion chromatography in the analysis of ionic liquid anions and cations.Our discuss mainly focuses on three aspects of the application of ion chromatography,namely,the determination of ionic liquid cations by ion chromatography,the determination of ionic liquid anions by ion chromatography and the simultaneous determination of ionic liquid anions and cations by ion chromatography.This paper also prospects the development of the determination on ionic liquids by ion chromatography.
