　　对碱熔后ICP-AES法测定复杂二次资源物料中钌含量的干扰情况进行了研究。Al、Si、Zr、Mo、Zn、Fe、Ca、Ti、Ta、Mg等元素对Ru的测定存在不同类型的干扰：Al、Ni基本不干扰测定，Na、Si、Ba等主要体现为基体干扰，其它元素则主要为光谱干扰。对钌含量较高(>10%)的样品，碱熔后以ICP-AES直接测定，能获得比较满意的结果。但钌含量太低时，碱熔后无论采用ICP-AES直接测定法还是标准加入法，均不能得到满意的结果。钌的二次资源物料组成较复杂，可在ICP-AES测定前采用蒸馏或其它方式分离，消除干扰。

The interference on the determination of ruthenium in the secondary resource materials by ICP-AES was discussed. The influence of Al, Si, Zr, Mo, Zn, Fe, Ca, Ti, Ta, Mg etc on determination of Ru is different. There is no interference of Al, Ni on the determination of Ru, but Na, Si, Ba etc are mainly embodied in the matrix interference, and the other elements is spectrum interference. For the high content Ru (>10%) samples, the alkali fusion-ICP-AES method can get a satisfied result. However, for the low content Ru samples, it is difficult to achieve an accurate result whether the direct determination method or the standard addition method after alkali fusion. Ru must be separated from the other elements by distillation or other method to avoid interference before determination.
