Various authors [14] have used the Stern-Langmuir equation in a simple form to describe the adsorption of surfactant ions on mineral surfaces,... 

Assuming no lateral interactions between the adsorbed species we may derive [9] the "Stern-Langmuir" equation... 

In order to calculate this distribution equilibrium of the liquid charge between the two layers (which may be called the Stern-layer and the Gouy-layer, respectively). Stern proceeds in a way somewhat analogous to the derivation of the adsorption isotherm of Langmuir. We will simplify Stern s equations by considering only the counter-ions, i.e. 

The basis for the discussion of adsorption on charged surfaces is the surface complexation model. The precept for this model is the use of the standard mass-action and mass-balance equations from solution chemistry to describe the formation of surface complexes. Use of these equations results in a Langmuir isotherm for the saturation of the surface with adsorbed species. There are of course other models that satisfy these precepts, but which are not generally referred to as surface complexation models, for example, the Stern model (J).
