Disinfection by-products are a type of harmful by-product produced by the reaction of disinfectants with natural organic substances during the disinfection process. The halogenated benzoquinones disinfection by-products are a class of potentially toxic chemical substances produced during the disinfection process that are detected at trace levels in water. In recent years,studies have found that their existence is potentially associated with the onset of bladder cancer. This article reviews the sample preparation techniques and instrumental analytical methods for the analysis of halogenated benzoquinones disinfection by-products in water,including sample preparation techniques such as liquid-liquid extraction,dispersion liquid-liquid microextraction,solid-phase extraction,and solid-phase microextraction,and gas chromatography-mass spectrometry,high performance liquid chromatography,ultra performance liquid chromatography,liquid chromatography-mass spectrometry and other instrumental analytical methods. The application of the above methods in the detection of halogenated benzoquinones disinfection by-products in actual water samples was introduced. The future development of halogenated benzoquinones disinfection by-products detection technology was prospected.
