| 中文摘要: |
| 采用微波消解技术处理冰铜样品，选择As 188.979 nm、Hg 194.227 nm为分析谱线，建立了电感耦合等离子体原子发射光谱法（ICP-AES）测定冰铜中砷和汞。实验表明：此方法可将试样溶解完全。砷检出限 3.1 ug/g、汞检出限0.7 ug/g，该方法操作简便、快速，该方法的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。 |
| 英文摘要: |
| The sample of copper matte was treated by microwave digestion method. As 188.979 nm and Hg 194.227 nm were selected as the analytical lines. A determination method of arsenic and mercury content in copper matte was established by inductively coupled plasma atomic emission spectriometry(ICP-AES). The results showed that the sample of copper matte could be completely dissolved by this method. The detection limit for arsenic is 3.1 ug/g and for mercury is 0.7 ug/g. The method is 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. |
