Application and progress of XRF in rare earth analysis

X-ray fluorescence spectrometry (XRF) is an effective tool for elemental analysis. Its fast, nondestructive and simultaneous determination of multiple elements can meet the analysis needs of rare earth elements. It plays a very important role in many fields such as geology, metallurgy and so on. Since the 21st century, the development of rare earth industry and the reuse of secondary resources has paid attention to the synchronous research and development of XRF analysis methods. This paper summarizes the development of X-ray fluorescence spectroscopy in recent years, the improvement of sample preparation methods, the optimization of rare earth analysis methods and its application in the analysis of composition, micro region distribution and species transformation, in order to provide reference ideas for the development and popularization of XRF technology in rare earth analysis.
