摘　　要：全氟烷酸化合物(PFAAs)是一类新型的持久性有机污染物,其环境污染与健康问题已经成为全球关注的热点问题。PFAAs缺乏紫外或荧光官能团,不能用常规的液相色谱/紫外检测器(LC/UV)或荧光检测器(FD)进行分析,同时PFAAs难以挥发,也不能用气相色谱(GC)进行分离检测。当前定量分析环境介质中的PFAAs多采用液相色谱-质谱联用技术(LC/MS),但是LC/MS法检测成本高,难以推广,还存在基质干扰效应等问题。因此,有必要发展衍生化LC或GC色谱分析法用于PFAAs的分析。本文综述了近年来衍生化技术用于PFAAs色谱分析的发展,通过与LC/MS进行比较,讨论了衍生化色谱分析法的优缺点、应用范围及研究意义,以期为相关研究提供参考。Perfluorooctanoic acid （PFOA）, perfluorooctane sulfonate （PFOS） and related perfluoroalkyl acids （PFAAs） are a group of new emerging persistent organic pollutants, leading to concern over their effects on humans and wildlife. Since PFAAs have not ultraviolet or fluorescent chromophores and are hardly volatile, they can not be analyzed by conventional methods such as liquid chromatography with ultraviolet detection （UV） or fluorescent detection （FD） and gas chromatography （GC）. Thus, analysis of PFAAs is mostly carried out by liquid chromatography-mass spectrometry （LC/MS）, which is very expensive and can not be applied widely. Moreover, LC/MS suffers from matrix interferences and other problems. Thus, it is necessary to develop derivatization techniques for LC or GC chromatographic analysis of PFAAs. The progress in derivatization followed bychromatographic analysis for PFAAs is reviewed in this paper. Then, the advantages and disadvantages, application and significance of these methods are discussed. It is aimed to provide more information for further study.
