应用便携式比色计测定水中氨氮

Determination of ammonia-nitrogen in water by portable colorimeter

本文采用便携式氨氮比色计简便、快速、准确地测定水中氨氮指标,与国标方法(水杨酸-次氯酸盐光度法)测量结果基本一致,满足现场快速分析测定氨氮的要求。

In this paper, the potable colorimeter was used to measure the concentration of ammonia-nitrogen in water. The method was simple, rapid, sensitive, and has no significant difference comparing with the national method. The method was appropriate for analysis of ammonia-nitrogen on site in place of the national method.
