  The aim of the paper is to study the renormalizations of the charge and of
the screening length that appear in the large-distance behavior of the
effective pairwise interaction between two charges in a dilute electrolyte
solution, both along a dielectric wall and in the bulk. The electrolyte is
described by the primitive model in the framework of classical statistical
mechanics and the electrostatic response of the wall is characterized by its
dielectric constant.
