一、前言 X射线荧光光谱分析具有谱线简单,快速准确,分析元素范围广,检测浓度范围宽,对样品状态适应性强等优点。由于X射线的特征谱线几乎与元素的物理状态和化学性质无关,故这种方法可以弥补化学方法之不足,成功地分析化学元素性质极为相似的稀土、铌钽、锆铪、钙镁等。我所使用的仪器是单道X射线光谱仪,可测元素范围从9号氟到92号铀。对于我室研制的催化剂作元素定量是适用的。
I. Introduction X-ray fluorescence spectrometry has the advantages of simple spectral line, fast and accurate analysis of a wide range of elements, a wide range of detection concentration, adaptability to the sample state and so on. Due to the fact that the characteristic line of X-ray has almost nothing to do with the physical state and chemical properties of the elements, this method can make up for the lack of chemical methods and successfully analyze rare earths, niobium-tantalum, zirconium-hafnium, calcium and magnesium with similar chemical element properties. The instrument I used was a single-channel X-ray spectrometer with measurable elements ranging from No. 9 to No. 92 uranium. For my room catalyst for the quantitative element is applicable.
