摘要
饮用水消毒副产物(DBPs)是消毒剂和一些天然有机物(NOM)反应生成的化合物,主要包括三卤甲烷(THMs)、卤代乙酸(HAAs)、卤代乙腈(HANs)和致诱变化合物(MX)4类。本文针对氯、氯胺、二氧化氯、臭氧4种主要消毒方式产生的消毒副产物,讨论了有关分析技术的发展过程,从DBPs的前处理技术、分析技术等角度,介绍了DBPs研究领域近期所取得的进展,并展望了今后研究的发展方向。
Disinfection by-products （DBPs） come mainly from the reaction of disinfectant and natural organic matter （NOM）. Usually, there are four important kinds of DBPs, which are trihalomethanes（THMs）, haloacetie acids （ HAAs）, haloacetonitriles （HANs） and mutagen X（MX）. Focusing on the DBPs of chlorination, chloramines, chlorine dioxide and ozone disinfection process, the paper has discussed the development of the related analysis methods. The sample pretreatment and analytical techniques of DBPs have been reviewed. The possible development trends and some suggestions on this field have been presented.
