摘要
采用JY-ULTIMA2型等离子光谱仪直接测定纯度99.8%～99.999%的氧化镥中的14种稀土杂质,选择了仪器的最佳工作条件。在选定条件下,14种稀土元素的检出限为0.04μg/g～2.5μg/g,对不同含量的氧化镥样品,加标回收率为93%～109%。方法简单、快速、准确,精密度好,已用于产品的检测。
A method for the determination of rare earth impurities in lutetium oxide has been developed.The operation condition of instrument was optimized working condition. The detection limits for 14 elements are 0.04~2.5μg/g.The method is accurate, rapid and convenient. It has been successfully applied to the determination of rare earth impurities in lutetium oxide samples with satisfactory results.
