饮用水含氮消毒副产物N-亚硝基二甲胺(NDMA)作为一种新发现的饮用水消毒副产物,由于其具有高致癌风险,已逐渐成为水环境化学研究领域的一个热点。本文介绍了NDMA产生的相关背景,讨论了其在饮用水处理过程中的生成机理,并详细评述了液液萃取(LLE)、固相萃取(SPE)和固相微萃取(SPME)等NDMA样品前处理技术以及气相色谱(GC)、气质联用(GC-MS)、高效液相色谱(HPLC)和液质联用(LC-MS)等NDMA检测技术。
As a newly discovered disinfection by-product of drinking water, N-nitrosodimethylamine (NDMA), a nitrogenous disinfection by-product of drinking water, has become a hot spot in the field of water environment chemistry due to its high carcinogenic risk. This paper introduces the relevant background of NDMA and discusses its formation mechanism in the process of drinking water treatment. The NDMA samples such as liquid-liquid extraction (LLE), solid-phase extraction (SPE) and solid-phase microextraction (SPME) Pretreatment techniques and NDMA detection techniques such as gas chromatography (GC), gas chromatography-mass spectrometry (GC-MS), high performance liquid chromatography (HPLC) and liquid chromatography-mass spectrometry (LC-MS)
