The analytical conditions and coexisting element interference have been studied. The sample can be directly determined by acid solution erosion.

对测试条件和共存元素干扰进行了研究，样品采用酸浸溶解、直接测定。

The optimal experimental conditions were obtained by matrix element match, background coefficient and element interference coefficient correction as well as element internal standard method.

本体系采用基体匹配、背景系数和元素干扰系数校正及元素内标法确定了最佳综合实验测试条件。
