摘要
随着我国环境标准日趋严格,硝酸盐作为水体污染的重要标志,越来越被人们所重视。综述了近年来水中硝酸根的测定方法,主要包括分光光度法、催化动力学法、离子色谱法、气相分子吸收光谱法、流动注射分析法。介绍了各方法的反应体系、线性范围、检出限、应用对象等,还探讨和展望了水中硝酸根测定方法的研究方向和发展前景。
More and more people pay attention to nitrate which is an important symbol of the pollution in water, since the environmental standards are getting stricter and stricter. The new development of the determination of nitrate in water is introduced. It mainly includes the new achievement of researches on spectrophotometry, catalytic kinetics method, ion chromatography, gas-phase molecular absorption spectrometry, flow injection analysis etc. The indicator reaction, system, linear range, and applications of the methods are involved. At the end, the development tends and application perspectives for the determination of nitrate in water in the future are discussed.
