Theoretical investigation of a polarizable colloid in the salt medium

In the present work, we have extended a weak coupling theory (Bakhshandeh a al., 2011) for systems with added 1:1 electrolyte. To study the accuracy of the developed theory, we compare its numerical predictions with Monte Carlo simulation data and a recent theory which accounts for the surface polarization. A very good agreement is found for the case of monovalent electrolytes, up to very high salt concentrations and different colloidal charges.
