摘要
Passivating effect of sodium salts of phenylanthranilic acids on iron in neutral borate buffer solution containing 10 mmol/l NaCl are studied. It is shown that the derivatives of the acid passivate the prereduced iron, as well as prevent its local depassivation by chlorides, better than do the unsubstituted ones. Adsorption of inhibiting anions at a surface of both reduced (at E = -0.65 V) and oxidized (at E = 0.2 V) is studied by ellipsometry. Types of isotherms are determined, free adsorption energies of some compounds are estimated; their comparative analysis shows that sodium salt of flufenamic acid has the best adsorbability.
