Ions approach an interface
differently depending on the forces in play. Ions are non-specifically adsorbed (positively
or negatively) when they are subjected in the interphase
only to long-range coulombic interactions (attraction or repulsion). They are believed
to retain their solvation
shell, and in the position of closest approach to the interface
they are separated from it by one or more molecular layers.
