The study of self-assembled films of triazole on iron electrodes using electrochemical methods, XPS, SEM and molecular simulation

3-Alkyl-4-amino-5-mercapto-1,2,4-triazole (AAMT) has been evaluated as corrosion inhibition for iron in 0.1 M H2SO4 when the films of AAMT were self-assembled on the surface of iron. The films of AAMT inhibitor were characterized by electrochemical impedance spectroscopy, electrochemical polarization curves Results revealed that AAMT performed excellently as a corrosion inhibitor for iron in H2SO4 solution. Surface analysis was carried out using X-ray photoelectron spectroscopy and scanning electron microscope. The mechanism of adsorption was discussed using molecular simulation.
