Kisil E.P. Voltammetric analysis of inorganic scintillation materials. —
Manuscript.

Thesis for a candidate’s degree in chemical science by speciality
02.00.02 — analytical chemistry. — Kharkov state university, Kharkov,
1999.

The results of researches in the field of the inorganic scintillation
materials analysis are given in the dissertation. 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 one- and
multielemental 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 the 110-7…110-3 %;

· evaluation of activator distribution (n10-6…m10-1 %) in scintillation
crystals and 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 scintillation
materials;

· control of entrance and spreading of technical inorganic
contaminations at production of scintillation materials.

Key words: voltammetric analysis, microadmixtures, dopants, main
components, toxicants, mercury electrodes, scintillation materials,
crystals, environment.
