水中9种以上亚硝胺类化合物的分析方法
摘要：
本发明涉及一种检测水中9种以上亚硝胺类化合物的分析方法，所述亚硝胺类化合物包含N-亚硝基二甲基胺、N-亚硝基甲基乙基胺、N-亚硝基二乙基胺、N-亚硝基二丙基胺、N-亚硝基二丁基胺、N-亚硝基吡咯烷、N-亚硝基哌啶、N-亚硝基吗啉和N-亚硝基二苯基胺，所述分析方法包括如下步骤：采用固相微萃取对待测水样进行萃取处理；和采用气相色谱串联质谱法(GC-MS/MS)对亚硝胺类化合物进行测定。本发明的方法实现了以快速、便捷、灵敏的测定水样中的多种亚硝胺类化合物的含量，分析效率高，具有较好的推广前景。
摘要（英）：

The invention relates to an analysis method for detecting more than 9 nitrosamine compounds in water. The nitrosamine compounds comprise N-nitrosodimethylamine, N-Nitroso-ethyl methylamine, N-Nitrosodiethylamine, N-nitrosodipropylamine, N-nitrosodibutylamine, N-nitrosopyrrolidine, N-nitrosopiperidine, N-nitrosomorpholine and N-nitrosodiphenylamine. The analysis method comprises the following steps of: extracting a water sample to be detected by adopting solid phase micro-extraction; and determining the nitrosamine compounds by adopting a gas chromatography tandem mass spectrometry (GC-MS/MS). The method provided by the invention achieves rapid, convenient and sensitive determination of the content of various nitrosamine compounds in the water sample, and has the advantages of the high analysis efficiency and the better popularization prospect.
