Abstract:
      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.
