Ionic liquid based on imidazolium cation to modify functional materials on separation of active compounds

Ionic liquids with imidazolium as cation are usually synthesized with different types of imidazolium cations, substituents, and anions. This review mainly focuses on of imidazolium-based ionic liquids in the field of modifying functional materials applied on separation of active compounds, especially on chromatographic separations ((high performance liquid chromatography (HPLC) and gas chromatograph (GC)) using materials based on imidazolium...
