摘要
采用硫酸沉淀分离基体元素铅后,ICP-AES 直接测定铅锭中 Te、Cr、Co、Ni 杂质元素。试验证明在本文提供的条件下 Se 会以 PbSeO_3的形式与 PbSO_4共沉淀,而 Te、Cr、Co、Ni 等待测元素则保留在溶液中。待测元素加标回收率在86.4%～108.4%之间。
The content of Te,Cr,Co,Ni was determined after base element Pb was precipitated with H_2SO_4 and separated from ingot lead.The results are satisfactory.The method has been applied to deter- mine trace impurity elements in ingot lead.
