Ion correlations in the electrical double layer near liquid/liquid interfaces

ORAL

Abstract

Equilibrium properties of the electrical double layer of monovalent salts near the interface between two immiscible electrolyte solutions are studied via Monte Carlo simulations, for several electrolyte concentrations. The corresponding results are collated with experimental data and the classical Verwey-Niessen theory of point ions. The observed differences between the simulation data and the mean field approach of ``back-to-back" electrical double layers stresses the importance of including properly ionic correlations near dielectric discontinuities.
