采用ICP-AES测定高含量锌、镉和铜,选择了最佳仪器工作条件和样品处理方法。在实验优选条件下,对铜镉渣中铜的含量为8%—12%;镉的含量为35%—38%;锌的含量为21%—23%进行了测定。回收率分别为铜99.8%—100.0%,镉98.3%—99.9%,锌99.3%—99.5%。 Determination of high levels of zinc, cadmium and copper by ICP-AES, opti- mum instrument operating conditions and sample handling methods were selected. Under the optimal experimental conditions, the content of copper in copper-cadmium slag is 8% -12%, the content of cadmium is 35% -38%, and the content of zinc is 21% -23%. The recoveries were 99.8% -100.0% copper, 98.3% -99.9% cadmium, 99.3% -99.5% zinc, respectively.
