加热柱芯电极发射光谱测定化探样品中痕量金砷铋锑

Determination of Trace Elements in Geochemical Samples by Emission Spectrometry with a Heating Axis Electrode

  • 摘要: 探讨了加热柱芯电极的蒸发和激发过程。利用ZnO为载体,Fe_2O_3作增强剂,MgO作稳定剂,碘溶液作卤化剂,样品不需化学预富集,使测金的检出限达到1:5万化探扫面要求,同时还可测定砷、铋、锑。各元素检出限分别为:1.l×l0-9Au,lx10-6As,0.l×l0-6Bi,2×l0-6Sb,试样分析的RSD(n=10)在4.2%~19.8%范围,质量符合要求。
