谱线宽度法测定粉末样品中高含量锡

THE DETERMINATION OF HIGH CONTENT TIN IN POWDER SAMPLES BY LINE WIDTH METHOD

本文利用谱线宽度方法测定了钽锡矿物样品中高含量元素Ｓｎ，讨论了外加内标元素Ｐｂ的含量分别在１％、２％和３％时对分析结果的影响。实验结果表明，Ｐｂ的不同加入量使得光谱分析的准确度和精密度有所变化。

The quantitative determination of 60% Sn in tantalum tin mineral samples was carried out by line width method.When the concentrations of internal standard element Pb in all three standard series was 1%,2%,and 3% respectively,the influence of Pb to the analytical results was discussed.The experimental results show that the different contents of the internal standard are different for both the accuracy and precision of spectral analysis.
