Application of a density functional approach to nonuniform ionic fluids: the effect of association
In the present paper we discuss a density functional approach for nonuniform ionic fluids, which takes into account the existence of ion pairs. The theory is based on a fundamental measure theory of hard-spheres, the theory of Gillespie et al., which leads to a more accurate description of the e...

Digital Library of Periodicals of National Academy of Sciences of Ukraine| Zusammenfassung: | In the present paper we discuss a density functional approach for nonuniform
ionic fluids, which takes into account the existence of ion pairs. The
theory is based on a fundamental measure theory of hard-spheres, the
theory of Gillespie et al., which leads to a more accurate description of the
electrostatic part of the grand potential as well as on Wertheim’s association
theory. The results of model calculations indicate that the inclusion
of the associative term in the grand potential leads to the structure of the
double layer, which differs from the structure evaluated by neglecting the
association. These differences are important at low temperatures only |
