摘　　要：卤乙酸是生活饮用水氯化消毒过程中的副产物之一,因其具有一定致癌致畸性而受到广泛关注。最新的《生活饮用水卫生标准》(GB 5749-2022)已将二氯乙酸和三氯乙酸设为水质常规指标,并将一碘乙酸设为参考指标,因此有必要更深入地汇总比较各种卤乙酸的标准检测方法。系统综述了中国、美国、日本检测卤乙酸的各种标准方法的发展优化历程,包括气相色谱法、离子色谱法和液相色谱法。对比了各国卤乙酸的达标限值,总结分析了三种仪器测定方法的优劣和选择性使用条件,以期为制定更加完善的卤乙酸检测体系提供参考。Haloacetic acids(HAAs)are by-products commonly produced during the disinfection of drinking water,and the occurrence of HAAs garnered considerable attention due to their toxic effects such as cytotoxicity and carcinogenicity.Standards for Drinking Water Quality(GB 5749-2022)establishes maximum contaminant levels for dichloroacetic acid and trichloroacetic acid as regulatory monitoring compounds.Additionally,monoiodoacetic acid is designated as monitoring indicator.Therefore,it is necessary to summarize and compare the standard detection methods of various HAAs.The optimizing process of standard analytical methods for HAAs in China,the United States,and Japan were herein reviewed,including gas chromatography,ion chromatography,and liquid chromatography.Moreover,the maximum contaminant levels of HAAs in the water quality standards of various countries were compared,and the advantages and disadvantages of the analytical methods and conditions of analysis are summarized.By synthesizing this information,the review aims to offer insights that could contribute to the development of an enhanced detection system for HAAs.
