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.<\/strong><\/p>\n<\/div>\n<\/div>\n\n\n\n<p><strong>Key publications:<\/strong><\/p>\n\n\n\n<p>Nesterov, S.V., Zakurdaeva, O.A., Sokolova, N.A., Rudakova, T.A., Feldman, V.I. <strong>Conformational insight into radiation-chemical transformations of dicyclohexano-18-crown-6 complexes with alkaline earth metal chlorides: Effect of cation size <\/strong>\/\/ Radiation Physics and Chemistry, 2019, 164, 108368.
