Abstract: | The behavior of uranyl fluoride complexes containing different isotopic species 16O-U-16O]2+, 16O-U-18O]2+, 18O-U-18O]2+ in isopropanol solutions under UV irradiation was studied. The rate of decrease in concentration of uranyl complexes containing isotopic species 16O-U-18O]2+ is higher than that for uranyl containing 18O-U- 18O]2+ species. It was shown that this phenomenon is not caused by difference in extinction energy of vaious isotopic species. |
