On the application of the associative mean spherical approximation to the ion-dipole model for electrolyte solutions

摘要

The solution of the associative mean spherical approximation for the ion-dipole model of an electrolyte solution is simplified and analyzed. It is shown that the description of this model can be reduced to a system of three coupled non-linear algebraic equations for ion-ion, ion-dipole and dipole-dipole energy parameterJ(0), b(1)(0) and b(2). A possibility of introducing ionic and dipolar scaling parameters Gamma(B) and lambda is discussed. Analytical expressions for the thermodynamic functions and solvent static dielectric permittivity are presented. (C) 2018 Elsevier B.V. All rights reserved.
