摘要
液相微萃取技术(LPME)是一种新型的样品前处理方法,具有快速、简单、廉价、选择性强、准确度高、溶剂消耗量少、环境污染小等优点,方便与各种分析仪器联用。其具有多种模式:单滴液相微萃取(SDME)、中空纤维液相微萃取(HF-LPME)、分散液相微萃取(DLLME)、悬浮固化液微萃取(SFODME)、连续流动微萃取(CFME)、直接悬挂液滴微萃取(DSDME)等,具有很好的研究潜力和应用前景。对液相微萃取技术在农药残留分析中的应用研究进展进行了综述。
Liquid phase microextraction （LPME） is one of novel sample pretreatment techniques which has many advantages such as quick, simple, economic, highly selective and accurate, less-solvent consuming and environmental friendly. It can be matched easily with most of analytical instruments. It includes several types such as single drop microextraction （SDME）, hollow fiber liquid phase microextraction （ HF-LPME ）, dispersive liquid-liquid microextraction （ DLLME ）, solidified floating organic drop microextraction （ SFODME ）, continuous-flow microextraction （ CFME ） and directly- suspended droplet microextraction （DSDME） etc. It is a very potential sample pretreatment technique for theoretic and application studies. In this review, the historical development and overview of these miniaturized liquid phase extraction methodologies were discussed and a comprehensive collection of application of these methods for preconcentration and determination of pesticide residue in various matrices were summarized.
