摘　　要：采用微波消解技术处理冰铜样品,选择As188.979nm、Hg194.227nm为分析谱线,建立了电感耦合等离子体原子发射光谱(ICP-AES)法测定冰铜中砷和汞的方法。实验表明,所拟定的方法可将试样溶解完全。砷检出限3.1μg/g、汞检出限0.7μg/g,方法操作简便、快速,其测定值与传统方法的测定值相符。加标回收率在95%~110%、相对标准偏差小于4%,可满足冰铜中砷和汞的准确测定。A determination method of arsenic and mercury content in copper matte was established by inductively coupled plasma atomic emission spectriometry(ICP-AES),with As 188.979 nm and Hg194.227 nm as the analytical lines.Experiments show that the proposed method could completely dissolve the sample,the detection limit for arsenic was 3.1μg/g and for mercury was 0.7μg/g.The method was simple and fast.The elements recoveries ranged from 95%to 110%,and the relative standard deviation was less than 4%,this method could reach the determination requirements of arsenic and mercury content in copper matte.
