饮用水中卤乙酸生成的影响因素及检测方法

Influential Factors and Analysis Method of the Formation of Haloacetic Acids in Drinking Water

卤乙酸作为已检出的氯化消毒副产物中最具致癌性的一类物质,在饮用水的研究中得到了越来越多的重视。本文从卤乙酸的生成机理及其影响因素、检测方法入手,对卤乙酸的研究进行了概述,并着重分析了影响卤乙酸生成的各种影响因素以及其检测方法的优化。

As one of the highest carcinogenic matters of the chlorinated disinfection by-products （DBPs）, haloacetie acids （HAAs） in drinking water have attracted more and more attention. The formation mechanism and influential factors of HAAs formation are discussed in this paper. Further more, the paper gives emphasis on the influential factors of HAAs formation, such as precursor types, reaction conditions, seasonal changes,types of disinfectors and biodegradation of HAAs.
