Abstract

IR spectroscopy was used to identify and study the structure and properties of domestic and foreign samples of ionites synthesized for the nuclear industry. The mechanism of uranium absorption from complex salt solutions and the interaction of uranium with functional groups of ionites were investigated. The changes in the structural and chemical properties of ionites subjected to prolonged commercial use were estimated. The dependence of the process of uranium sorption on anionites and the dynamics of accumulation of silicon compounds in the anionites were found. A comparative analysis of the data showed that the capability of an anionite to absorb silicon does not always interfere with uranium sorption. 6 figures, 2 tables, 9 references.
