稀土分离过程中常出现仅含有几个稀土元素的中间产物,产物的组分数据对研究稀土元素的分离机理及规律具有重要意义。X-射线荧光光谱法分析稀土元素已有许多报导。溶液法对稀土含量低的试样其荧光强度较低,同时在真空条件下溶液法又比较复杂。然而在研究分离稀土的过程中有时仅有几十mg试样。为此本法选用了试样用量少的薄试样的滤纸片法。薄试样法应用的比较多,六十年代初期已有过推荐和报导。由于稀土元素的离
Rare earths often appear in the process of separation of rare earth elements containing only a few intermediates, the composition of the product data to study the mechanism of rare earth elements and laws of separation of great significance. There have been many reports on the analysis of rare earth elements by X-ray fluorescence spectrometry. Solution method for the low content of rare earth samples fluorescence intensity is low, while the solution under vacuum conditions and more complicated. However, there are sometimes only a few dozen mg of sample in the study of rare earth separation. For this reason, this method uses a thin sample of the sample less filter paper method. Thin sample method is more applied, the early 1960s have been recommended and reported. Due to the rare earth elements from
