Abstract:The state of mineral-like uranovanadates of mono- and bivalent metals in aqueous solutions was studied. Based on experimental solubility data, the reaction equilibria in the crystal uranovanadate-aqueous solution system were described quantitatively, which, in turn, allowed evaluation of the solubility products of uranovanadates and their standard Gibbs energies of formation and prediction of the solubility of these compounds in aqueous solutions of various compositions under the isobaric-isothermal conditions.
