Kisil' O. Voltammetric analysis of inorganic scintillation materials

The conditions of voltammetric determination of microadmixtures, dopants, main components in scintillation materials, and of toxicants in environmental objects have been studied, using different types of mercury dropping and stationary electrodes. On the basis of the studies a complex of analysis procedures has been developed, which enabled to solve a number of problems which are of importance for material science: reliable control of microadmixtures in n(10-7...m(10-3 %; the evaluation of activator distribution (n(10-6...m(10-1 %) in scintillation crystals; establishing of the ratio of europium valence forms in KCl(Eu) crystals; evaluation of deviations from stoichiometry for tungsten (VI) oxide; determination of main components from small weights of materials; control of entrance and spreading of technical inorganic contaminations.
