| 摘 要： | 本文详细论述了压片法及熔融片法测定钼精矿的分析条件。其中压片法通过大量采用同一矿区的生产样品经化学定值后作为校准样品建立校准曲线,因此粒度效应和矿物效应基本上可可忽视。文章详细地讨论了元素之间谱线干扰、背景和脉冲高度选择。使用经验系数法校正基体效应,可准确测定钼精矿中的钼、硫、铁、铜、铅、锌等11个元素。在熔融片法主要讨论了元素谱线的选择及其相互之间的干扰。

| Abstract: | The article discussed the analysis condition of molybdenum concentrate by pressed pellet and fused bead thoroughly. In the pressed pellet method, lots of production samples from the same mine are used as calibrated samples to create cablibration after chemical analysis, and the particle size effect and mineral effect can almost be ignored. The article exhaustively discussed element line-overlap ,the selection of background and PHD. The Mo,S,Cu,Pb,Zn etc 11elements can be accurately determined in molybdenum by experience coefficient correction. In the fused bead method ,the line selection and overlap was mainly discussed. |
