摘要
建立了ICP-OES法测定分银渣中锡含量的分析方法。试样用氢氧化钠、碳酸钠熔融,热水浸出,盐酸酸化,在光谱仪上直接测定锡的含量。锡的检出限为0.0065μg/mL,加标回收率在98%～103%,测定结果的相对标准偏差为1.77%～5.19%。方法流程短,简单快速,易于掌握。
The content of tin in silver separating residue was determined using ICP-OES method. The sample was melted with sodium hydroxide and sodium carbonate, leached with hot water and acidified with hydrochloric acid. The detection limit of tin is 0.0065μg/ml. The standard recovery rate is 98%~103%. The relative standard deviation of the measurement results is 1.77%~5.19%. The method process is short, simple, quick and easy to master.
