A general approach to the calculation of adsorption of cations and anions on clay and oxide surfaces is presented. It is shown that the known Gouy-Chapman and Stern models for cation adsorptions are particular cases of the general approach. Six equations should be used simultaneously to solve the adsorption of cations and anions on charged surfaces, after adjusting the proper parameters. The complex adsorption of phosphate on montmorillonite was successfully solved using this approach. The effect of the living root on changes in the parameters needed to solve these equations is discussed.
