摘　　要：本文介绍了粉末压片法制样、X射线荧光光谱法测定氧化铥富集物中10种稀土元素含量的分析方法。以D.Jongh数学模式对谱线干扰和基体效应进行校正,得到满意的工作曲线。方法的回收率为95.50%～105.00%,相对标准偏差为0.057%～2.530%,该方法简便快速、结果准确,能满足日常分析工作的要求。This paper reports the method for the determination of ten rare earth elements in Tm2O3 concentrate by X-ray fluorescence spectrometric method and power pressed method. D. Jongh mathematical model corrects the sample spectral interference and matrix effect and gets satisfactory working curve. The recovery rate of the method is in the range of 95. 50% ～ 105. 00% and the relative standard deviation is in the range of 0. 057%～2. 530%. The method is simple and rapid,and its results are accurate,which can meet the need of the daily analysis work.
