N2 - The influence of the lyophilic properties of an electrode on the specific adsorption of ions is analyzed by comparing the electric double-layer structure at mercury, bismuth and eutectic (In + Ga) alloy in acetonitrile and dimethylsulfoxide in inactive electrolyte solutions and in solutions containing surface-active ions. A method is proposed for estimating the free energy of interaction of solvent molecules with the electrode surface from adsorption isotherm parameters. It is shown, as exemplified by dimethylsulfoxide, that the lyophilic series of metals established from differential capacity values in inactive electrolyte solutions correlates with the change in the values of the free energy of interaction of dimethylsulfoxide molecules with the electrode, estimated by the method proposed in this paper. The influence of the nature of the electrode and the salvation energy of ions in different solvents on the surface activity series of these ions is examined.
