Outer-sphere surface complex
– A water molecule is present between the surface functional group and the bound ion or molecule (Sposito 1989). Outer-sphere complexes involve electrostatic coulombic interactions. Outer-sphere complexation is usually a rapid process that is reversible, and adsorption occurs only on surfaces that are of opposite charge to the adsorbate
