摘要
试样用HNO3与HCl溶解,ICP-AES法直接测定富银渣中0.01%～5%的Ag、Au、Cu、Ni、Sb、Bi、Zn、Al、As、Sn等元素。研究了溶剂、试样中铅及其它共存元素的干扰,选择了合适的分析线。加标回收率在99.6%～107.1%,相对标准偏差为0.59%～3.08%,方法准确、简便、快速。
The samples were dissolved in HNO3-HCI. The ICP-AES method was used to determine directly Ag, Au, Cu, Ni, Sb, Bi, Zn, Al, As, Sn in the rich Ag residue. The interference from Pb and other coexisting elements was investigated, and the optimum analyzing bands were selected. The standard recovery rates are from 99.6% to 107.1%, The relative standard derivation of 0.59% to 3.08% is reached. The method is accurate, simple and rapid.
