水中痕量亚硝胺类消毒副产物的分析测试技术

Analytical technologies of trace N-nitrosamines as disinfection by-products in water

亚硝胺类消毒副产物由于其潜在的高致癌风险正引发国内外水处理领域的极大关注。水中痕量亚硝胺的定量分析测试技术是开展各项研究工作的基础。介绍了水中常见亚硝胺消毒副产物主要单体物质的基本特征;探讨了识别定量分析水中亚硝胺消毒副产物所面临的主要困难和关键问题;从样品的预处理技术和测试技术两个方面论述了目前水中痕量亚硝胺消毒副产物定量分析的主要进展。

Due to their potentially high carcinogenicity,several N-nitrosamines have attracted great attention as disinfection by-products in drinking water.Analytical testing techniques for these N-nitrosamines in water were the foundation of all the related research.Characteristics of the co-mmon N-nitrosamines as disinfection by-products in drinking water were reviewed.The pre-concentration problems and key techniques for quantification analysis of the N-nitrosamines in drinking water were discussed,and the quantitative analysis development of the trace N-nitrosamines as disinfection by-products in drinking water was presented from the aspects of pre-treatment and testing techniques of samples.
