水中消毒副产物的监测方法研究进展

含氯、含氧等杀菌类消毒剂在饮用水生产、废水排放、再生水利用等环节应用广泛，会与水中的前驱物通过取代、氧化还原、水解、加成等反应形成种类繁多的消毒副产物（DBPs）。DBPs的靶标监测基于已知DBPs的特性如挥发性、半挥发性、不挥发性等，采取相应的前处理和仪器分析方法；非靶标鉴别可对大量未知的DBPs进行筛查。综述了三卤甲烷、卤乙酸、卤代苯醌、卤代酚、卤代硝基甲烷、卤代羟基呋喃、N-亚硝胺等7类常见DBPs的靶标监测方法，以及水中DBPs的非靶标鉴别方法，并从重视监测、完善环境监测与评价方法、加强环境管控等方面提出了今后DBPs的监测与管理建议。

Research Progress on Monitoring Methods for Disinfection By products in Water

Disinfectants containing chlorine and oxygen were widely applied in drinking water production, wastewater discharge and reclaimed water use, and would react with precursors in water through substitution, redox, hydrolysis and addition to form a wide variety of disinfection by products (DBPs). Based on known characteristics, such as volatile, semi volatile and non volatile, the target monitoring of DBPs adopted corresponding pretreatment and instrumental analysis methods. Non target identification was suitable to screen a large number of unknown DBPs. The target monitoring methods for seven kinds of common DBPs, such as trihalomethanes, haloacetic acids, halobenzoquinones, halophenols, halonitromethanes, halogenated hydroxyfurans, N-nitrosamines, and non target identification methods of DBPs in water were reviewed. Some suggestions for DBPs monitoring and management in the future were put forward from the aspects of paying attention to monitoring, improving environmental monitoring and evaluation methods and strengthening environmental control.
