摘要
利用AA3型连续流动分析仪测量水中氨氮,分别对标准物质及稀释过程、标准曲线、测量的重复性、检测方法几个方面引入的不确定度进行评定。氨氮测量结果为(1.23±0.066)mg/L;k=2。
Ammonia nitrogen in water is determined by using AA3 Type （CFA）. The uncertainties of standard material as well as the dilution process, standard curve, repeatability and detection methods are evaluated. The determination result of ammonianitrogen is （1.23±0. 066） mg/L; k =2.
