食品与环境样本中有机氯农药残留的净化技术研究进展

Application of clean-up and determination techniques for analysis of organochlorine pesticides in different matrix

在查阅大量相关文献并结合作者自身研究工作经验的基础上,根据介质中干扰物的种类和特点,按照不同介质进行分类,重点介绍了填充柱、固相萃取、凝胶色谱、磺化和基质固相分散等净化技术在检测分析水、土壤、沉积物、茶叶、中药以及脂肪性样本中有机氯农药残留中的应用。认为将净化技术与提取技术或分析技术有效结合,提高样品净化效率及整体分析速度将是未来净化技术的主要发展趋势。

Different clean-up methods,including packing column,solid phase extraction,gel permeation chromatography,sulfonation,mixture solid phase disperse and so on,were introduced.Then,the utilized of those clean-up techniques in the residue analysis of organochlorine pesticides（OCPs） in water,soil,sediment,tea-leaf,Chinese medicine and fatty sample were introduced according to the type of the matrix after consulting lots of literatures and author＇s work experience.It was believed that various purification techniques could be well combined with extraction techniques or detection techniques.This is useful to increase the whole analysis speed and will be the development trend of purification technique for OCPs.
