| 摘 要： | 以石墨碳粉(含氟化钠、碳酸钠、氧化镓等混合物载体)为缓冲剂,采用三标准试样法绘制锑(Sb)元素的标准工作曲线,对钨精矿中微量Sb的光谱分析法进行研究。该法对Sb元素的检出限为0.003%,测定结果非常接近于化学法。

| Abstract: | The emission spectrometry of trace antimony in tungsten concentrate was studied.The graphite powders was employed as the buffering agent containing the mixture carrier of sodium fluoride,sodium carbonate and gallium oxide.The standard working curve of antimony is drawn based on three-standard-sample method.The Sb detection limit of this spectrometry is 0.003% and its determination results are very close to those obtained by chemical method. |
