The method of calculating the parameters of electric double layer and constants of the acid-base equilibria for magnetite,
titanium oxide (IV) and aluminum oxide by studying of the dependence of adsorption of chloride ions at various pH values.
The applicability of the virial adsorption isotherms and Graham-Parsons theory to describe the parameters of acid-base
equilibria on the boundary of the oxide / electrolyte interface was shown.
he key words: magnetite, oxides, Graham-Parsons model, the adsorption of ions, the electric double layer theory of the
"related places".
