An Improved Closure of the Born-Green-Yvon Equation for the Electric Double Layer.

Abstract

An extensive series of calculations are made to compare an improved closure of the Born-Green-Yvon (BGY) equation for the electric double layer of primitive electrolytes to existing Monte Carlo simulation and other theories, such as the modified Poisson Boltzmann (version: 5) (MPB5) and the Hypernetted chain/mean spherical approximation (HNC,MSA), and its recent improvements. In contrast to these theories the BGY equation satisfies the contact theorem always. Furthermore the bulk pair correlations function used are the most accurate available, namely the HNC bulk results. The results show very good general agreement to the computer work for high densities and surface charges. In particular higher densities are obtained than those hitherto published in the literature. For low density 2-2 and 2-1 electrolytes the agreement is not as good for the other theories. Keywords: Primitive Model of Charged Interfaces Integral Equations.
