| 摘 要： | 目的:给出火焰原子吸收分光光度法测定滤膜中镍的测量不确定度。方法:不确定度的主要来源为标准物质的不确定度,标准曲线的不确定度,以及测量重复性引起的不确定度,计算出各种不确定度分量并将其合成,以计算出滤膜中镍测量结果的不确定度。结果:按数学模型计算滤膜中镍的浓度为17.21μg/张,扩展不确定度为0.55μg/张,结果表达为17.21±0.55μg/张。结论:该方法适用于火焰原子吸收法测定滤膜中镍的不确定度评定。

| Abstract: | Objective：To find the measurement uncertainty of determination nickel in filter membrance.Methods：The main sources of the combined uncertainty were considered,such as stand solution uncertainty,stand curve uncertainty,uncertainty induce by repeatablity of measurements.The components of uncertainty and the combined uncertainty were calculated.Results：The concentration of the nickel in filter membrance was 17.21μg calculated according to mathematical model established in the present study,expanded uncertainty was 0.55μg,and the expression of the uncertainty was（17.12±0.55）μg.Conclusion：This method can be used for evaluation of uncertainty of determinatiion of nickel in filter membrance by FASS. |
