X射线荧光光谱灰化薄样法测定铥镱镥富集物中九个重稀土元素

X RAY FLUORESCENCE SPECTROMETRLC DETERMINATION OF NINE HEAVY RARE EARTH ELEMENTS IN THE ENRICHED MIXTURE OF THULIUM OXIDE,YTTERBIUM OXIDE AND LUTECIUM OXIDE BY ASMING THIN FILM TECHNIQUE

本文提出了一种灰化薄样制样法，ｘ射线荧光光谱分析铥镱镥富集物中九种重稀土元素氧化物。方法具有标样制备简单、消耗纯稀土量少、标准样片易保存、制样成本低等优点。该法已用于稀土产品铥镱镥富集物的分析。

A method for the determination of nine heavy rare earth elements in the enriched mixture of thulium oxide ytterbium oxide and lutecium oxide by XRF method has been studied in this poper.The samples were prepared by ashing thin film.This method is characterized as it is low cost,economic and simple in standards preparation,and standards can be easily preserved.The accuracy and precision of the results were satisfactory for the demands of prodnction.
