摘要
本文采用GB/T 8538-2008《饮用天然矿泉水检验方法》中的流动注射在线蒸馏法对生活饮用水中总氰化物测定中产生的不确定度进行分析,确定其不确定度主要来源于几个方面:(1)氰化物标准物质的质量浓度;(2)检测样品的重复性测量;(3)流动注射在线蒸馏法的标准曲线拟合;(4)标准溶液曲线的配制和稀释过程。建立不确定度的数学模型。
In this paper, the GB/T 8538-2008 drinking natural mineral water testing methodof flow injection occurring in the process of cyanide in water detection uncertainty is analyzed. The uncertainty mainly comes from cyanide concentration of standard material quality; repeatability of measurement; flow injection sample standard curve fitting; the configuration of the standard curve and the dilution process. To establish the mathematical model of uncertainty.
