原子吸收光谱法测定高纯稀土氧化钇中钙量干扰效应分析条件的优选

A Measurement of Interferent Effects of Calcium in High Pure Rare Earths Y_2O_3 With Atom Absorption Spectrometry

目的 :研究原子吸收光谱法测定高纯稀土氧化钇中钙量干扰效应分析条件。方法 :本文用正交试验设计[1 ]对高纯稀土氧化钇中钙测定时 ,对基体和酸度的干扰进行了试验。结果 :基体和酸度的干扰表现为与分析元素无关。此外 ,仪器工作条件的改变 ,可不同程度产生干扰。结论 :此方法快速、准确。

Objective:TO study the atom absorbs the spectrum method measurement interferent effects of calcium in high pure rare earths Y 2O 3.Method:The interference effect of the basic body and acid in calicium content of high pure the sparse soil Y 2O 3 was determined by Atomic abscrption spectrometry with handing over to experiment the design.Result:It was found that the interference effect of the basic body and acid was not related to the concentration of calcium and change of working conditions of instrument counld produce interferece.Conclusion:The method is rapid and precise.
