Abstract

THE INHIBITION effect of 3-(6- sodiumsulfonate hexayloxy) …...aniline monomeric surfactant (MC6) and the analogues polymer poly 3-(hexayloxy sulphonic acid) aniline (PC6) on the corrosion of aluminium in 0.5 M HCl solution was investigated with weight loss and potentiodynamic polarization techniques. The results show that the inhibition occurred through the adsorption of inhibitor molecules on the metal surface. The inhibition efficiency was found to increase with increasing of inhibitor concentration and decrease with increasing temperature. It was found that these inhibitors acted as mixed–type inhibitors with anodic predominance. The adsorption of these compounds on the metal surface obeyed the Langmuir and Frumkin adsorption isotherms. Thermodynamic functions for both the dissolution and adsorption processes were determined. The obtained results from weight loss and potentiodynamic polarization techniques are in good agreement.
