Abstract

The composition and stability of uranyl citrate complexes in aqueous solutions of the ionic medium of 1M-(H,Na,(UO₂)_0.5)A₃ (where H₃A represents citric acid) were studied based on the potentiometric and spectrophotometric data. The best fit to the experimental data was obtained with the set of complexes UO₂A^-, (UO₂A)₂^2-, HUO₂A, (HUO₂A)₂, and H₂UO₂A⁺, the former three complexes being significant in the whole concentration region.
