| 摘 要： | 本文评定了火焰原子吸收测定土壤中镍含量的测量不确定度。以标准土壤样品(GSW 17401)为测试对象,通过应用火焰原子吸收法测定土壤镍含量,对其测量不确定度的来源、计算和结果表示等问题进行探讨。样品消解前处理产生的不确定度最大,标准曲线拟合测定溶液产生的不确定度其次。在测定中前处理和标准曲线拟合测定溶液应给予足够重视,以减小测量不确定度。

| Abstract: | Taking the measurement process of Ni content in standard soil samples (GSW 07401) as the measurement object, the uncertainty was estimated in this paper for determining Ni in soil by using flame atomic absorption spectrometry. The uncertainty generated by pre-treatment sample digestion was largest, followed by the standard curve fitting to determine the solution uncertainty. Thus, adequate attentions should be given to the pre-treatment and the standard curve fitting to determine the solution in order to reduce the measurement uncertainty. |
