摘　　要：全氟辛酸(PFOA)和全氟辛烷磺酸(PFOS)是典型的全氟类有机污染物,在土壤、水、食品和生物样品均有检出。PFOA和PFOS具有超疏水性,紫外吸收较弱甚至没有。实际样品中,往往和众多同系物共存且含量低,因此分离和检测都较为困难。本文从常规分析测试角度出发,概述了我国近5年各类样品中PFOA和PFOS的提取方法,介绍了常用的色谱及色谱质谱联用的检测方法,为PFOA和PFOS的检测工作提供了一些参考。Perfluorooctanoic acid(PFOA)and perfluorooctanesulfonic acid(PFOS),which can be detected in soil,water,food and biological samples,are typical perfluorinated organic pollutants.PFOA and PFOS are superhydrophobic,with weak or even no UV absorption.In samples,PFOA and PFOS often coexist with many homologues and their contents are low,so it is difficult to separate and detect them.In this paper,the extraction methods of PFOA and PFOS in various kinds of samples in recent 5 years in China are summarized,and the common detection methods of chromatography and chromatography-mass spectrometry are introduced,which provides some reference for the detection of PFOA and PFOS.
