| 摘 要： | 本文以盐酸和硝酸在比色管中,在水浴环境下直接溶解样品,最大限度避免元素挥发损失和外界污染。电感耦合等离子体发射光谱仪,测定铜精矿中的有害杂质元素砷和汞。实验结果表明,汞回收率为98%~102%,砷的测定结果与国家标样值吻合。砷相对标准偏差(RSD)(N=11):0.65%,汞相对标准偏差(RSD)(n=11):1.28%。方法操作简单,分析快速,结果准确。

| Abstract: | Copper concentrate Samples were resolved by HCL-HNO3 in waters,maximum of efficiency to avoid element loss or pollution,and then determination of arsenic and mercury content in copper concentrate by ICP-AES. The analytical results of arsenic agree well with those obtained by the national srandard method, retrieve rate of mercury in the rang of 98%-102%,RSD（n=11）（As）：0.65.RSD（n=l 1）（Hg）： 1.28.The method operate easy,analysis fast, exact result. |
