A possibility of using S,N-containing sorbents for the analysis of materials based on rare earth element compounds with the determination of impurities in the sorption concentrate by arc atomic emission spectrometry is studied. The properties of S,N-containing sorbents in aqueous solutions and various rare earth matrices are studied. A methodological approach to the sorption preconcentration of impurities in REE-based materials followed by a direct analysis of the sorption concentrate by arc atomic emission spectrometry is described. The results of the development of a spectrochemical method for determining impurities in rare earth element materials are presented, and performance characteristics are evaluated.
