Uranyl(VI) nitrate salts: Modeling thermodynamic properties using the binding mean spherical approximation theory and determination of "fictive" binary data

Article Abstract:

The thermodynamic properties of highly concentrated aqueous solutions of uranyl nitrate at 25 degree Celsius are described. A new resolution of the binding mean spherical approximation (BIMSA) theory, taking into account 1-1 and also 1-2 complex formation, is developed and used to reproduce, from a simple procedure, experimental uranyl nitrate osmotic coefficient variation with concentration.

Experimental determination of water activity for binary aqueous cerium(III) ionic solutions: Applications to an assessment of the predictive capability of the binding mean spherical approximation model

Article Abstract:

The predictive capability of the binding mean spherical appproximation (BIMSA) theory is adopted to describe the thermodynamic properties of electrolytes in the case of aqueous solutions of lanthanide(III) nitrate and chloride salts. Concentrated binary solutions of cerium nitrate are prepared in order to measure experimentally water activity and density as a function of concentration.

Lanthanide salts solutions: Representation of osmotic coefficients within the binding mean spherical approximation

Article Abstract:

Osmotic coefficients of aqueous solutions of lanthanide salts are described using the binding mean spherical approximation (BIMSA) model based on the Western formalism for association. An expression for the osmotic coefficient, derived within the BIMSA, is used to fit data for a wide variety of lanthanide pure salt aqueous solutions at 25 degree Celsius.
