摘要
悬浮固化液相微萃取集采样、萃取、浓缩于一体,具有富集效率高、成本低、有机溶剂用量少,易与气相色谱(GC)、高效液相色谱(HPLC)、原子吸收分光光度仪(AAS)联用等特点,是一种环境友好的样品前处理新技术。本文对悬浮固化液相微萃取的基本原理、影响萃取率的因素和目前的应用研究进展进行了简要评述。
The liquid phase microextraction（LPME） based on solidification of floating organic drop,which incorporated sampling,extraction and concentration into a single step,was a new environmentally benign sample-preparation technique.This novel technique proved to be low-cost and virtually organic solvent-free and could provide a high enrichment factor.It can be easily manipulated for the combination use with gas chromatography,high-performance liquid chromatography and atomic absorption spectrometry.The basic prin-ciples,parameters affecting the extraction efficiency and recent applications of the solidification of floating organic drop liquid phase microextraction are briefly reviewed in the paper.
