Abstract

In this paper, the desirable physical-chemical properties of ionic liquids, the method of ionic liquids used as running electrolytes or modifier in aqueous and non-aqueous capillary electrophoresis were introduced. The potential of capillary electrophoresis based on ionic liquids was discussed throughout the paper. The application status of capillary electrophoresis based on ionic liquids in the analysis of the bioactive components in traditional Chinese herbs, polyphenols, basic proteins, metal ions, and so on were reviewed and summarized with the illustrative use of recent literatures. In addition, the foreground of capillary electrophoresis based on ionic liquids, as well as its difficulties was also discussed.
