| 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. |
