摘　　要：同位素分析技术测定硝酸盐氮的丰度来确定污染源,可以从根本上控制水体中硝酸盐氮的来源。稳定氮同位素的组成不同,氮的来源也不同。介绍了同位素分析法的基本原理及来源不同的硝酸盐氮的丰度值,同时阐述了国内外稳定氮同位素分析的几种预处理方法的适用条件和限制因素。提出了目前硝酸盐氮同位素分析预处理中存在的问题,并对未来发展方向做了综述。The abundance of nitrate nitrogen was determined by isotope analysis to determine the sources of pollution. The sonrces of nitrate in water could be controlled fundamentally. The composition of stable nitrogen isotope was different, and the nitrogen sources were also different. The basic principles of isotope analysis and the abundances of nitrate nitrogen in different sources were introduced ; meanwhile several pretreatment methods, the applicable conditions and limiting factors of the stable nilrogen isotope analysis in domestic and overseas were illustrated. The current problems in the pretreatment for nitrate nitrogen analysis were proposed, and the future development directions were reviewed.
