REGULARITIES OF ADSORPTION OF IONS AND SURFACTANTS ON METAL CORROSIONPRODUCTS AND SALT DEPOSITS

The adsorption of ions at the oxide-solution interface is described us ing assumptions about the existence of acid-base equilibria and propos itions of the Graham-Parsons theory on the double electric-layer struc ture. The adsorption data are shown to be in good agreement with the t heoretical predictions. The data on the effect of the solution pH on t he adsorption of a number of organic surfactants at the oxide-solution interface are discussed. The data on the adsorption of surfactants on salts (silver iodide and calcium carbonate) are discussed with specia l reference to the structure of the double electric layer.
