Abstract
Molal activity coefficients of uranyl nitrate and nitric acid in mixed solutions were calculated on the basis of Mikulin’s equations. Analytical equations for calculating these quantities at different concentrations were obtained. These equations are compatible with published activity coefficients for binary solutions, which allows their use for calculating the equilibria in uranium extraction from nitric acid solutions.
