Expert Consensus on the Application of Ion Chromatography in the Detection of Ammonia Nitrogen in Drinking Water
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.
