火焰原子吸收光谱法测定铜精矿中银含量结果的不确定度评定

Uncertainty evaluation for determination of Ag content in copper concentrate by flame atomic absorption spectrometry

通过火焰原子吸收光谱法对铜精矿试样中银含量测量的重复性,测定用试样中银含量,试剂空白液中银含量,试样的定容体积,试样的质量等不确定度分量的评定,求得铜精矿中银含量测定结果的不确定度。

The combined uncertainty was obtained by analyzing and quantifying the uncertainty of measuring repeatability, Ag content in reagent blank, the constant volume and the quality of samples.
