最近的研究表明，一氯胺可以与某些有机化合物发生反应 氮前体普遍存在于饮用水中，且特征不明显 天然有机物（NOM）生产N-亚硝二甲胺（NDMA）。名字 然而，人们对相关反应知之甚少。本文报道了 一氯胺氧化NOM与NDMA形成的相关性。这个 还研究了预氧化对NDMA形成的影响。接触预氧化剂 如游离氯、高锰酸盐或过氧化氢会降低NDMA 随后与一氯胺接触时的形成电位。线性关系 NDMA形成电位的降低与NOM光谱之间也存在差异 特征变化，如SUVA272。这些信息不仅可以帮助您深入了解 NDMA前体的性质以及与NDMA形成有关的反应 还提出了一些减少饮用水处理中NDMA形成的策略。包括14个参考文献、图表。

Recent studies have shown that monochloramine can react with certain organic nitrogen precursors that are ubiquitous in drinking water as well as less characterized natural organic matter (NOM) to produce N-nitrosodimethylamine (NDMA). The NOM involved reactions are nevertheless poorly understood. This paper reports on the correlations between NOM oxidation by monochloramine and NDMA formation. The influence of pre-oxidation on the formation of NDMA is also studied. Exposure to preoxidants such as free chlorine, permanganate or hydrogen peroxide reduces the NDMA formation potential in the subsequent contact with monochloramine. Linear relationship is also found between NDMA formation potential reduction and NOM spectral characteristics changes such as SUVA272. This information not only provides insight into the nature of the NDMA precursors and the reactions involved in NDMA formation, but also suggests some strategies to minimize NDMA formation in drinking water treatment.
