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