硝酸盐氮是生活饮用水中的重要监测项目。硝酸盐氮的检测方法主要有可见分光度法,离子色谱法,紫外分光光度法。国家生活饮用水的标准检测方法中尚未有离子选择性电极法,而电极法在各种检测分析中已有大量的应用。 Nitrate nitrogen is an important monitoring item in drinking water. Nitrate nitrogen detection methods are visible spectrophotometry, ion chromatography, UV spectrophotometry. There is no ion-selective electrode method in the standard test methods for drinking water in the country, but the electrode method has been widely used in various detection and analysis.
