摘要：
Dispersive liquid-liquid uncroextraction (DLLME) is a novel environmentally benign sample-preparation technique, possessing obvious advantages of simplicity of operation, low-cost, high enrichment factor and low consumption of organic solvent. Compared with single drop microextraction (SDME) and hollow fiber-based liquid-phase microextraction, the extraction time of DLLME is greatly shortened. DLLME coupled with gas chromatography, high performance liquid chromatography and atomic absorption spectrometry, etc., has been widely applied in the analysis of environmental and food samples. The basic principles, parameters affecting the extraction efficiency, and the latest applications of DLLME are reviewed.
