摘要
对N-亚硝基二甲胺(NDMA)的物化特性、水体中的来源、分析检测方法以及去除与控制工艺等研究进展进行了全面综述,并提出了未来的研究方向。由于NDMA特殊的物化性质,对该物质的检测和处理都有相当的难度。目前传统的检测方法还不能满足检测要求,需要建立快速、准确、可检测较低浓度NDMA的新型检测方法。对NDMA的去除主要是采用紫外线辐射处理工艺,但工程实践证明该方法性价比不高,因此,新型经济、有效的去除工艺及控制方法亟待研发。
The physicochemical properties of N-nitrosodimethylamine （ NDMA）, sources of NDMA in water, detection methods of NDMA, and methods for NDMA treatment and control were reviewed, and the main research directions in the future were given. Due to the special physicochemical properties of NDMA, it is difficult to detect and remove NDMA. The conventional detection method cannot meet the detection requirement, thus, it is necessary to establish a new detection method that can detect low-concentration NDMA rapidly and accurately. The most common removal method of NDMA is UV radiation treatment process, but it is not a cost-effective technology. New type technologies need to be researched and developed for NDMA control.
