五氯酚及其钠盐的样品前处理方法和残留检测技术研究进展

Research progress on sample preparation method and residue detection technology of pentachlorophenol and its sodium salt

五氯酚作为一种持久性有机污染物,曾被用作杀虫剂、抗菌剂和防腐剂等,其性质稳定且不易降解。残留于环境中的五氯酚及其钠盐五氯酚钠(统称PCPs)可以通过生物富集作用进入食物链,进而残留于动物性食品中。本文综述了国内外PCPs的相关标准和法律规定,并比较了中国关于PCPs的不同标准,分析了不同基质中PCPs的样品前处理方法和常用检测技术,对食品中PCPs的残留检测技术研究和应用前景进行了展望。

As a persistent organic pollutant,pentachlorophenol has been used as an insecticide,fungicide,and preservative,etc.It is stable and not easily degraded.The residues of pentachlorophenol and its sodium salt(PCPs)remaining in the environment can enter the food chain through bioconcentration and then remain in animal foods.In this article,the relevant standards and legal regulations of PCPs in China and other countries were reviewed,and the different standards of PCPs in China were compared.The sample preparation methods and common analysis and detection technology of PCPs in different matrices were compared and analyzed.The research and application prospects of the residue determination technology of PCPs in foods were prospected.
