水质氨氮测定方法研究进展

摘要

指出了水中氨氮含量是反应水质状况的重要参数,综述了近年来国内水质氨氮测定方法的研究进展,依次讨论了纳氏试剂分光光度法、水杨酸分光光度法、电极法、气相分子吸收法等各方法的优缺点.最后,简要对其未来的发展趋势进行了展望.%The content of ammonia nitrogen in water is an important parameter of water quality.This paper discussed major advances on the determination of ammonia nitrogen in China.It highlighted the advantages and disadvantages on Nessler's reagent spectrophotometry, salicylic acid spectrophotometry, ion selective electrode method, gas-phase molecular absorption spectrometry and other assays.Finally, the paper forecasted a brief perspective on its future development trends.
