The relationship between hydrophobicity of triazoles and their adsorption and passivation ability in relation to copper is analyzed.Adsorption of triazoles on oxidized copper surface is polymolecular.Adsorption of the first monolayer is described by Frumkin equation with the free energy of adsorption in the range of 51-70 kJ/mol.Certain triazoles are able to effectively inhibit anodic dissolution of copper in neutral chloride solutions.The possible spatial arrangement of the triazoles on the surface of oxidized copper is revealed.
