Thermodynamic properties of a polyelectrolyte solution containing a mixture of counterions differing in charge

摘要

From the solution of the Poissonndash;Boltzmann equation for the cell model of a polyelectrolyte solution with mixtures of counterions of different charge, the electrostatic internal and free energies, the degree of binding of counterions, the osmotic coefficient, and the heat of dilution are calculated. These thermodynamic properties are presented as functions of valences, and mole fractions of the counterions, and the possibility of their application for interpretation of the scarce experimental data is discussed.
