| 摘 要： | 对用氢化物发生原子荧光光谱法联合测定水中砷、硒的测量结果进行了不确定度评定。分析了测量不确定度的来源,如标准物质、样品取样体积、样品稀释体积、工作曲线的非线性及测量结果的重复性,对各不确定度分量进行了评定和计算。砷、硒含量测量的扩展不确定度均为5.28%。

| Abstract: | The uncertainty of measurement for the determination of arsenic and selenium in water by hydride generation atomic fluorescence spectrometry was evaluated. The uncertainty caused by the certified reference material, solution volume, standard curve, repeatability of results of measurements were evaluated and calculated respectively. The expanded uncertainly of measurement for Se,As were both of 5.28%. |
