电感耦合等离子体原子发射光谱法直接测定高纯氧化铈中14个稀土杂质的研究

Determination of Trace 14 Rare Earth Elements in Cerium Oxide by Inductively Coupled Plasma-Atomic Emission Spectrometry

本文研究了电感耦合等离子体原子发射光谱直接测定99.95%氧化铈中14种稀土杂质的方法。讨论了基体线和光带对分析线的干扰及扣除、并加入70％乙醇提高灵敏度,方法简单,再现性好,准确度高,得到了满意的结果。

A method for direct determination of trace 14 rare earch elements in cerium oxide (99.95％) by inductively coupled plasma-atomic emission spectrometry has been studied. The interference of light-bands and matrix on the analytical lines and the deduction for the interference were studied. The addition of 70％ alcohoI in the sample solution determined leads to the improvement of the sensitivity. The method is simple, rapid and accurate with good reproducibility.
