富钇氧化物中钇的X射线荧光光谱法测定

DETERMINATION OF YTTRIUM IN Y-RICH OXIDE BY X-RAY FLUORESCENCE SPECTRUM METHOD

拟定了 X 射线荧光光谱法测定富钇氧化物中钇的方法.试验表明,微量溶液滤纸片制样,以锶为内标,X 射线荧光光谱法测定,有较好的精密度和准确度.

A method is proposed to determine yttrium in Y-rich oxide.The exper- iments show that if the micro-solution filter paper is used for making sample and stron- tium is taken as internal standard,the determination of yttrium by X-ray fluorescence spectrum method will result in high precision and accuracy.
