Abstract

The inhibitive eftect of iron corrosion in 1M HCI by p-aminophenol and poly (p-amino phenol) were investigated by the polarization and electrochemical impedance spect-roscopy methods. The effectiveness of poly(p-aminophenol) is very high in comparison with that of monomer. The results showed that p-amino phenol and poly (p-amino phenol) suppressed both cathodic and anodic processes of iron dissolution in 1M HCI by their adsorption on the iron surface according to Langmuri's adsorption isotherm. The inhibition efficiency of both p-amino phenol and polyp-amino phenol) were found to increases with the inhibitor concentrations.
