Abstract:

Ionic liquid (IL) have gained extensive applications in the fields of extraction and separation due to their unique
properties, such as low vapor pressure, high thermal stability, good solubility and designable structures. In the paper, the
characteristics of IL and the modes of ionic liquid-dispersive liquid-liquid microextraction are introduced. The recent
applications of this technique in the determination of contaminants in foods and the environment are emphatically reviewed.
Based on the above discussion, future exploration and development of this technique are also proposed.

Key words: ionic liquid (IL), dispersive liquid-liquid microextraction (DLLME), food, environment pollutant, application
