The safety issue of chlorination disinfection in drinking water has been paid more and more attention in the past decades. Since mineral ions exist widely in natural water and the slight pollution of heavy metals happens frequently, it is of great importance for evaluating and controlling the formation of disinfection by-products ( DBPs) to study the effect of metal ions on DBPs formation. In this paper, the research progress on the formation of the DBPs during drinking water chlorination in the presence of different metal ions was reviewed, and the investigation results in literatures about some typical metal ions and oxides, such as ferric ions, copper ions, manganese dioxide and lead oxide were introduced. The forming species, reaction mechanisms and affecting ways of DBPs formation were discussed. Authors hope to provide useful information for understanding and investigating the possible mechanisms and influence factors of DBPs during chlorination, and help the control of DBPs and the guarantee of drinking water safety.%饮用水氯化消毒的安全性问题一直是水处理领域的研究热点之一.由于天然水体中矿物质的普遍存在以及微量重金属污染的经常发生,开展金属离子对消毒副产物形成的影响规律研究,对于实际饮用水消毒副产物的控制及其对人类健康的影响评价都具有重要意义.本文以目前研究较多的一些典型金属离子和金属氧化物（如铜离子、铁离子、二氧化锰和二氧化铅等）为例,从饮用水消毒过程中副产物形成种类、反应机理、影响途径等几个方面,综述分析了近年来国内外有关金属离子对消毒副产物影响的研究进展,旨在为进一步了解和研究饮用水消毒副产物形成的影响因素及规律,科学控制饮用水消毒副产物并保障饮用水安全,提供参考和支持.
