This project is connected with the problems of developing radiation-resistant extraction systems and sorbents based on crown ethers for nuclear fuel processing and radioanalytical applications. The main attention is paid to the mechanisms of radiation-chemical transformations of crown-ethers of various structures, as well as to the study of the influence of the nature of the cation and anion on the radiation-chemical processes in crown-containing systems. Along with this, attempts are being made to develop original methods for obtaining crown-containing sorbents. To characterize the mechanisms of radiation-chemical transformations, EPR spectroscopy is used, various synthetic and analytical methods are used.
