- 摘要:
- 饮用水中卤代含氮消毒副产物（N-DBPs）是一类具有致癌、致畸、致突变等“三致”特性的消毒副产物。调研总结了世界范围内饮用水中卤代N-DBPs浓度水平及分布情况，汇总分析了卤乙腈、卤代硝基甲烷、卤代乙酰胺等前处理技术以及检测方法，系统比较了三类卤代N-DBPs的主要前体物和生成机制，提出了饮用水中卤代N-DBPs在检测分析与生成控制等方面的未来研究方向。
- Abstract:
- Halogenated nitrogenous disinfection by-products (N-DBPs) in drinking water are a class of disinfection by-products with the characteristics of carcinogenic, teratogenic and mutations. The concentration level and distribution of halogenated N-DBPs in drinking water worldwide is investigated and summarized. The pre-treatment technologies and detection methods of haloacetonitriles, halognitromethanes and haloacetamides are summarized and analyzed. The main precursors and formation mechanism of three kinds of halogenated N-DBPs are systematically compared. The future research direction of halogenated N-DBPs in drinking water in detection analysis and generation control is proposed.
