电感耦合等离子体原子发射光谱法测定高纯铼酸铵中Ca、Cd、Mn、Fe、Mg、Al、Cu、Co、Mo、Pb、Sn和Ni

Determination of Ca,Cd,Mn,Fe,Mg,Al,Cu,Co,Mo,Pb,Sn and Ni in High Purity Ammonium Rhenate by ICP AES

本文介绍了电感耦合等离子体发射光谱法（ＩＣＰ－ＡＥＳ）测定高纯铼酸铵中１２个杂质元素的方法。采用挥发分离基体，探讨了高铼酸铵基体的干扰及其消除办法。ＩＣＰ－ＡＥＳ测定结果的准确度和精密度均能满足分析要求。

This paper describes the new method for the determination of above title twelve impurity elements in ammonium rhenate by ICP AES,points out the interference from the rhenae matrix and elimination by evaporation technique.The lowest detectable content was 10 -5 %( W/W ) for above each element.The accuracy and the precision in the result of the ICP AES determination method meets the analysis requirement.
