摘要
本文通过连续流动分析仪测定肥料中钾含量,分别对标准物质及稀释过程,标准曲线,测量重复性,检测方法几个方面引入的不确定度进行评定。肥料中钾含量测定结果为(192.05±3.74)mg/L;k=2。
Potassium content in the fertilizer is determined by using SEAL Analytical. The uncertainties of standard material as well as the dilution process, standard curve, repeatability and detection methods are evaluated. The determination result of potassium is（192.05 ±3.74）mg/L;k=2.
