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%。

A method for determining zinc,copper and iron in electrolysis cadmium by FAAS was established.Under experimental conditions,characteristic mass are 0.006μg/mL/1% for copper,0.015μg/mL/1% for iron,0.003μg/mL/1% for zinc ,recovery is 97.5%—98.0% for copper,99.1%—100.2%for iron,97.4%—99.1% for zinc.
