On the modified Poisson–Boltzmann closure for primitive model electrolytes at high concentration
C.W. Outhwaite, L. B. Bhuiyan
Abstract
The modified Poisson-Boltzmann closure is applied to the Kirkwood hierarchy of integral equations to investigate high concentration primitive model electrolytes. Two approximations are considered in the two sphere fluctuation potential problem. The derived damped oscillatory mean electrostatic potentials suggest that this closure should be of use in providing a basis for understanding the large experimental decay lengths found at high electrolyte concentrations.
