电感耦合等离子体发射光谱法测定铥镱混合稀土料液中的氧化镥含量

Determination of The Lutetium Oxide in Thulium and Ytterbium mixed Rare Earth by Inductively Coupled Plasma Emission Spectrometry

本文对ICP-OES法测定铥镱混合稀土料液中的氧化镥含量进行了研究,采用基体匹配法消除了基体的干扰,实验确定了仪器最佳工作参数,样品的回收率在99.0%~101.5%,方法精密度(RSD)在1.41%~2.54%,该方法简便,快速准确,满足生产监控要求。

In this paper,the content of Lutetium oxide in Thulium and Ytterbium mixed rare earth material liquid was determined by ICP-OES method,the interference of the matrix was eliminated by matrix matching method,and the optimum working parameters of the instrument were determined by experiment,the recovery rate of the sample was 99.0%-101.5%,and the precision(RSD)of the method was 1.41%-2.54%.
