| 摘 要： | N-亚硝基二甲胺(NDMA)是一种强致痛物质,普遍存在于食品、工业制品和污染大气之中.作为一种新发现的饮用水消毒副产物,NDMA已逐渐成为水环境化学研究领域的一个热点.介绍了饮用水消毒副产物NDMA的相关背景,重点评述了NDMA在水中的形成机制,主要包括亚硝化和非对称二甲肼氧化两种途径,强调NDMA的前体物还有待进一步确认.对水中NDMA的去除方法进行了总结,包括物理方法、光解作用、生物降解和高级氧化技术.最后提出了饮用水含氮消毒副产物NDMA的若干研究方向.

| Abstract: | N-nitrosodimethylamine(NDMA) is a probable human carcinogen found in ng/L concentrations in chlorinated and chloraminated water.NDMA,a new-born disinfection by-product(DBP),would be the research hotspot in water environment field gradually.Relevant background of NDMA was introduced,and formation mechanism of NDMA was discussed including two pathways: nitrosification and indirect oxidation via unsymmetrical dimethyl hydrazine(UDMH) intermediate.Other formation pathways of NDMA and its precursors in water wer... |
