- Abstract:
- Nitrogenous disinfection by-products (N-DBPs), as a kind of emerging disinfection by-products in drinking water, have stronger teratogenic, carcinogenic and mutagenic effects compared with carbonaceous disinfection by-products (C-DBPs), and their concentrations are not limited and monitored by domestic standards and regulations, so their hazards are more hidden, and give rise to be widely concerned in recent years. In this paper, the toxicological properties, formation mechanism and control technology of new N-DBPs such as haloacetonitriles (HANs), haloacetamides (HAcAms), halonitromethanes (HNMs) and nitrosamine (NMs) were summarized, and the pre-treatment technology and principle of different N-DBPs in existing research were summarized.The application of the new materials in the pretreatment enrichment process were prospected, which provided a literature basis for the realization of trace detection and effective monitoring of N-DBPs in drinking water.
