摘要
本文以PbCl_2沉淀分离铅后,用ICP-AES法测定Pb-1号纯铅中的Sn、Zn、Fe、Mg、Cu、Ag和Ca等杂质的含量。方法对基体的分离效率在98％以上。杂质元素加料回收率为92％～120％,各元素测定的相对标准偏差分别为5.1％～12.5％。本法具有干扰小,准确度高,快速简便等优点。
A method for determination of trace impurities in Pb-1 pure lead by ICP-AES after precipitating PbCl2 is developed in this paper. The efficiency of separation of the matrix is more than 98%, the recovery of trace impurities is 92%-120%, and the RSD is 5.1%-12.5%. The advantages of this method are less interferences, better accuracy, more rapid and simple.
