| 摘 要： | 铜铁试剂是一种良好的沉淀剂。在5～10%的盐酸介质中,它能有效地沉淀Fe、Ti、Zr等,消除了测定过程中的光谱干扰。配以ICP-AES法测定稀土元素,其精密度和准确度均能满足地球化学样品分析的需要。此法对测稀土元素和钪非常有效。

| Abstract: | In 5-19% (v/v) HCl medium, cupferron is found to be an effective precipitant for Fe,
Ti and Zr. Their spectral interferences can thus be eliminated in the determination of REEs and
Sc f by ICP-AES. The precision and accuracy of the results meet the requirements of the geo-
chemical samples. |
