茶叶中农药残留分析技术研究进展

Review on Analytical Methods of Pesticide Residues in Tea

查阅近些年国内外公开发表的文献,简述了我国茶叶生产上常用农药情况,比较了国内外茶叶农药残留最大限量标准,综述了茶叶中农药残留的主要检测技术,重点对固相微萃取法、液相微萃取法、分散固相萃取法等样品前处理技术,以及气相色谱法、液相色谱法、质谱法、免疫分析法等检测技术在茶叶农药残留分析中的应用及特点进行了总结,并对其发展方向进行了展望,以期为今后开展茶叶中农药残留的分析研究提供参考。

Based on the recent published literatures,this paper briefly states the commonly used pesticides in China ＇s tea production,compares their domestic and international maximum residue limits,summarizes the relevant main detection techniques,concludes the application and characteristics of sample pretreatment technologies,such as solid phase microextraction,liquid phase microextraction,dispersive solid phase extraction,and analytical methods in the analysis of pesticide residues in tea samples,including gas chromatography,liquid chromatography,mass spectrometry,immunoassay. The future development trend about the analysis of pesticides in tea is also prospected. This review provides a reference for the further study on analytical methods of pesticides in tea.
