A local HNC/HNC and a HNC/HNC (hypernetted-chain) treatment of the double layer for 2:1 electrolytes is presented. The local HNC/HNC treatment produces improved structure information about the double layer. For divalent counter-ions, nonmonotonic co-ion profiles and improved charge inversions near the electrode are obtained as well as improved diffuse layer potentials; for monovalent counter-ions, packing layers build up at high surface charges. These are effects due to the treatment of the ionic correlations in non-neutral homogeneous systems with the local composition of the electrolyte in front of the electrode. At zero surface charge, a nonzero surface potential is obtained. © 1986 The American Physical Society.
