【摘要】 文章确立了熔剂金矿经火试金富集,利用ICP-AES法同时测定金、银、铂、钯量的分析方法。确定了合适的分析谱线和最佳工作条件。各元素的检出限均小于5μg/L,回收率为97.05%～104.63%,RSD为1.96%～4.36%。实际应用中获得满意结果。更多还原

【Abstract】 A method for determination of Au Ag Pt Pd elements in gold ore by ICP-AES after enrichment with fire assay has been developed. the optimum of the instrument was optimized, and the effect of matrix was studied. Under the optimized working condition, the detection limits for 4 elements were in the range of 2.7～3.8 μg /L. Recoveries of the elements were in the range of 97.05%～104.63%. The elements have been determined with RSD <4.36%. The method has been successfully applied in determination of Au Ag Pt Pd in gold ore with satisfactory results.更多还原
