对铂族元素中子活化分析中存在的 1 8种干扰核反应进行研究 ,由活化分析基本理论 ,计算出各种干扰核反应的影响系数 .计算表明 ,对于大多干扰核反应 ,当干扰元素为常量组分 ,而待测元素为微量组分时 ,干扰才变得明显 .但对于Au对Pt的二级干扰和U对Ru ,Pd的裂变干扰 ,即使当干扰元素为微量组分时 ,也可能产生明显的干扰 .
The 18 kinds of interfering nuclear reactions in the analysis of platinum group element neutron activation were studied, and the influence coefficients of various kinds of interfering nuclear reactions were calculated by the basic theory of activation analysis. The calculation shows that for most interfering nuclear reactions, when the interfering element is a constant component , But the interference becomes obvious when the element to be measured is a trace component.But for the secondary interference of Au to Pt and the interference of U to the fission of Ru and Pd even when the interference element is a trace component, Interference.
