Abstract

On the basis of consideration of hydration, hydrolysis, dissociation, polymerization, and ligand exchange that occur in aqueous solutions of U(VI) complexes, a new approach to the assignment of absorption bands of the ligands in electronic spectra of uranium(VI) carbonate complexes in the range 190–400 nm has been suggested. For the Na4[UO2(CO3)3] complex, the following assignment of absorption bands has been made: Na3[UO2(CO3)3]–, 258 nm; Na2[UO2(CO3)3]2–, 300 nm; and Na4[UO2(CO3)3], 330 nm.
