摘要
氨氮是环境监测中的重要指标,纳氏试剂比色法是测定氨氮的国家标准方法。该方法的前处理方式对结果的准确度影响较大。通过实验探讨了2种前处理方式对3种不同类型水样分析结果的影响,得出前处理方式的适用范围。
Ammonia nitrogen is an important indicator in environmental monitoring, determining ammonia nitrogen by nessler's reagent is the national standard method. The pretreatment method of this method has great influence on the accuracy of the results. In this paper, the effects of two pretreatment methods on the analysis results of three different types of water samples are discussed through experiments and the applicable scope of the pretreatment methods is obtained.
