饮用水中二甲基亚硝胺检测方法研究进展

Research progress on detection methods of dimethylnitrosamine in drinking water

综述了饮用水中痕量级含氮消毒副产物二甲基亚硝胺(Dimethylnitrosamine,NDMA)的检测方法和检测技术。通过分析水样预处理方法以及各种检测手段,对现有检测技术进行比较,并重点针对浓缩倍数、固相萃取吸附剂以及色谱条件等关键问题进行研究,以期为饮用水中痕量级的 NDMA检测提供科学的参考依据,为人们的饮用水卫生安全提供更高的保障。

It has introduced the detection methods and techniques of dimethylnitrosamine,which is a kind of trace nitrogen-containing disinfection by-products in drinking water.The existing detection techniques were compared by analyzing the pretreatment methods of water samples and test methods.And the key problems such as concentration multiple,solid-phase extraction adsorbent and chromatographic conditions were studied in order to provide scientific reference basis for the detection of NDMA in drinking water and provide higher guarantee for people’s drinking water safety.
