ICP-AES测定海绵镉中的镉和锌

Determination of Cadmium and Zinc in Sponge-Cadmium by ICP-AES

介绍了ICP-AES加标回收和校准曲线法测定海绵镉中Cd(30%—70%)锌(10%—30%),线性相关系数0.99999—0.99997,加标回收率94.08%—99.59%之间,RSD在0.12%—1.13%之间。

The amounts of Cadmium（30%—70%）and Zinc （10%—30%）in Sponge-cadmium were determined by ICP-AES with standard addition and standard working curve methods.The linear correlative coefficient is in the range from 0.99999 to 0.99997,recoveries are in the range of 94.08%—99.59% with RSD of 0.12%—1.13%.
