Arc atomic-emission analysis of rare-earth metals and their oxides

Rare earth metals are of strategic importance for all developed countries of the world community. Without them, modern wholesale and radio electronics, instrument and automotive industry, chemical industry, metallurgy, atomic and alternative energy are not complete. Areas of application and price for rare -earth materials directly depend on their purity. In this regard, the control of the chemical composition is an integral part of their production and consumption. Currently, relevant in the analytical control of rare -earth materials is the expansion of the circle of determined impurity elements and an increase in the sensitivity of the analysis.
This monograph describes a methodological approach to the development of improved techniques of arc atomic-emission analysis of rare-earth metals and their oxides, including both the direct definition of impurity elements and the combination of the instrumental approach to analysis with the preliminary separation of interfering elements, their harmonization with the capabilities of modern equipment, metrological and information support. This information is of interest to employees of analytical laboratories, research organizations, higher educational institutions and consumers of rare-earth metals and materials based on them
