| 摘 要： | 碘代消毒副产物(I-DBPs)是饮用水领域广泛关注的一类高毒性消毒副产物。综述了不同碘源下I-DBPs生成机制的最新研究进展,水中I-DBPs的碘源主要包括碘离子、碘系消毒剂、碘化显影剂等有机碘及最新发现的碘酸盐,天然有机物存在下,不同碘源在消毒处理过程中均可生成IDBPs。研究I-DBPs的不同碘源生成机制对于这种"三致性"消毒副产物的碘源前体控制进而削减其在饮用水处理过程中的产生具有重要的理论和现实意义。为控制I-DBPs的产生,对水体中的不同碘存在形态存在应予以关注,同时急需研发相关控制技术(如化学预氧化、深度处理、消毒方法优化等)来削减碘源前体的转化。

| Abstract: | Iodinated disinfection by-products (I-DBPs) are a class of emerging and highly toxic DBPs in drinking water field. The formation mechanisms of I-DBPs derived from different iodine sources were presented. Iodine sources that comprised formation of I-DBPs in drinking water could be sorted as naturally occurring iodide, iodine-based disinfectants, iodinated organic compounds such as iodinated X-ray contrast media, and iodate. Iodine sources could be transferred to I-DBPs by oxidation of disinfectants in the presence of natural organic matter. It is of important theoretical and practical significance to investigate the formation mechanisms of I-DBPs from different iodine sources in controlling them during drinking water treatment process. In order to control the formation of I-DBPs, more attention should be paid to the existence of different iodine species in waters. Meanwhile, it is urgent to develop related control techniques, such as chemical preoxidation, advanced treatment, and optimization of the disinfection methods to reduce the conversion of iodine source precursors to I-DBPs. |
