Abstract: Dispersive liquid-liquid microextraction (DLLME) is a novel sample preparation technique. It integrates extraction and condensation, and has the advantages of simple operation, short time consumption, low cost, high recovery rate, high enrichment factor and low environmental pollution. In this paper, the principle, procedures and influencing factors of DLLME are introduced. The recent applications of this novel technique in the analysis of pesticide residues in food and environment are also emphatically discussed. Moreover, its application prospect is proposed.

Key words: dispersive liquid-liquid microextraction (DLLME), pesticide residue, detection, application
