几种氨氮检测方法比较

Comparison of ammonia nitrogen detection methods

综述了我国水体中几种常见的氨氮检测方法,主要包括水杨酸分光光度法、纳试剂分光光度法、气相分子吸收光谱法、电极法。对几种检测方法的原理、试样要求及优缺点进行了评述分析,以期为我国水体中氨氮检测方法的选择提供参考。

This paper summarized several detection methods of ammonia-nitrogen in waters. Salicylic acid spectrophotometric method, Nessler＇s method, gas phase molecular absorption spectroscopy method and ammonia gas sensitive electrode method were introduced. The determination principle, sample pretreatment, advantages and disadvantages of these methods were also discussed. The results of this paper provide a reference for the selection of ammonia nitrogen detection methods.
