摘要:

 进入21世纪,硝酸盐氮氧同位素测试技术的显著进展是反硝化细菌法测试技术的建立。反硝化细菌法具有可同时分析浓度低至μg/L的硝酸盐氮氧同位素组成、免去复杂的样品预处理、分析时间大大缩短以及从复杂溶液中只转化NO3-为N2O等优点。实验过程由细菌挑选和培养、样品NO3-转化为N2O、N2O提取纯化、同位素测试以及同位素测试结果校正等几个关键步骤组成。国外研究结果显示该技术不仅可用于海水和淡水中硝酸盐同位素测试,而且还可用于土壤样品,并得到不断的完善和应用|国内建立了这一技术,在包气带和地下水硝酸盐污染研究中取得重要进展。由于该技术诸多优点,建议大力促进这一技术在我国的研究和应用,希望有关部门加大支持力度,进一步完善该技术并推广应用。

Abstract:

 In the 21st century, the significant advances in the measurement of nitrogen and oxygen isotopic compositions of nitrate are the development of analytical techniques of the denitrifier method. The method has many advantages, such as simultaneous analysis of nitrogen and oxygen isotopic compositions of samples with low NO3- concentrations down to μg/L, relief from complicated sample pretreatment, a large reduction in analysis time, only conversion of NO3- in samples to N2O in complex solutions and so on. The experimental procedure consists of several key steps including bacterium selection and cultivation, conversion of sample NO3- to N2O, extraction and isotopic analysis of N2O and correction of isotopic analytical results. Results from foreign researchers showed that the technique was applicable for the measurement from soil, seawater and freshwater, and was widely used. This technique was also developed in and obtained important advances in the contamination study of nitrate in the vadose zone and groundwater. Because of its advanced analytical technique, We suggest great efforts be given to its research and application in China. Concerned agencies in charge should give more support to the study so that the technique can be modified further and applied widely.
