摘要
Uranium oxide was dissolved in the form of the uranyl peroxo-carbonato complex ion, UO2(O2)(CO3)24− in carbonate solutions with hydrogen peroxide. When UO2(O2)(CO3)24− ions lose their peroxide component, they become a stable species of uranyl tricarbonato complex ion, UO2(O2)(CO3)24−. The uranyl peroxo-carbonato complex self-decomposed more rapidly into the uranyl tricarbonato complex ion in the presence of a metal oxide in the carbonate solution. In this study, decomposition of the uranyl peroxo-carbonato complex in a carbonate solution was investigated in the presence of several metal oxides using absorption spectroscopy.
