饮用水中氨氮测定：以纳氏试剂分光光度法为例

摘要

介绍了用纳氏试剂分光光度法测定饮用水中氨氮的方法。通过实验对该方法进行适用性检验,分析其精密度、准确度、标准曲线及最低检出浓度,探讨纳氏试剂分光光度法检测水中氨氮的特点。%The paper introduces the determination of ammonia nitrogen in drinking water with Nessler reagent spectrophotometry, and after testing the applicability of this method in experiments, analyzes its precision, accuracy and standard curve and the character- istics of determination with the minimum Nessler reagent spectrophotometry.
