Year: 2024
Type: article
Abstract: The chemical stability of Ln[(UO2)3O3.5(OH)2]·5H2O (Ln = La, Ce, Pr, Nd) compounds in aqueous solutions in a wide range of medium acidity was studied. The acid-base intervals of the existence of compounds in aqueous solutions have been established, and solubility was determined. Based on the data obtained, the equilibrium constants of heterogeneous reactions and the Gibbs function of Ln[(UO2)3O3.5(OH)2]·5H2O formation were calculated, solubility curves of the studied compounds were calculated, diagrams of the state of U(VI) and Ln(III) in aqueous solutions were constructed.
