摘　　要：氨氮可对水体环境、鱼类等水生生物造成危害,并且引起饮水卫生问题,因此成为水质的重要监测指标之一。现行氨氮国标检测方法存在操作繁琐、引入污染、干扰因素多等弊端。与国标方法相比,离子色谱法具有检测形态更稳定、特异性强、干扰因素少、操作简单、环境友好等特点,且其灵敏度高、准确度高、重现性好,在基层生活饮用水检测工作中更具优势,但目前该法尚未被纳入国标方法中。为顺应当前标准方法向无害化、仪器化方向发展的趋势,促进广大基层水质检测工作高效、便捷、环保展开,建议增加离子色谱法作为生活饮用水中氨氮的国标检测方法,替代纳氏试剂分光光度法。Ammonia nitrogen has become one of the important monitoring indicators of water quality due to its harm to aquatic environment,fish and other aquatic organisms,and sanitation problems caused in drinking water.The existing national standard method of ammonia nitrogen has many disadvantages such as cumbersome operation,pollution and interference.Compared with the current national standard methods,ion chromatography has the characteristics of more stable detection form,strong specificity,less interference factors,simple operation and environmental friendliness,and its high sensitivity,high accuracy and good reproducibility,which is more advantageous in the detection of grass-roots drinking water,but it has not been included in the national standard methods until now.To conform to the trend of the current standard methods towards harmlessness and instrumentalization,and to promote the efficiency,convenience and environmental protection of water quality testing at the grassroots level,it is recommended to add ion chromatography as an national standard method for the detection of ammonia nitrogen in drinking water,instead of Nesser′s reagent spectrophotometry.
