本文介绍了以石墨粉为载体,用粉末直流电弧法进行金属锑中微量杂质的光谱测定。可测定杂质含量范围为1×10~(-4)～1×10~(-2)%,相对误差在15%以内。
In this paper, the graphite powder as a carrier, powder DC arc method for the determination of trace impurities in the metal antimony spectrometry. The measurable impurity content ranged from 1 × 10 -4 to 1 × 10 -2% with the relative error within 15%.
