摘  要:
残留农药的含量极低,而且还与其同系物、异构体、降解产物、代谢产物等共存。农药残留前处理技术成为农药残留分析检测中的关键。作为一种新型的样品前处理技术,液相微萃取技术扮演着重要的角色。文章将介绍3种液相微萃取技术:中空纤维液相微萃取技术、顶空液相微萃取技术和分散液相微萃取技术,对这3种技术进行了比较,重点介绍了它们在农药残留物检测中的应用,并对液相微萃取技术的发展前景予以展望。

摘  要:
Pesticide residues were at a very low level.They also coexisted with their homologs,isomers,degradation products and metabolites etc.Pretreatment technologies of pesticide residues were the key of their analysis and detection.As a new pretreatment technology,liquid phase microextraction technology played an important role in sample preparation.Herein we would introduce three liquid phase microextraction technologies: hollow fiber liquid phase microextraction technology,head space liquid phase microextraction technology and dispersed liquid phase microextraction technology.These three kinds of technologies were compared,and their applications in pesticide residues detection being recommended.And the prospects of liquid phase microextraction technology were predicted.
