Abstract

Salicylidene-p-toluidine (SPT) was evaluated in this work as a corrosion inhibitor for APl X70 carbon steel in an acidic setting at 25°C using 1M hydrochloric acid. The study was based on gravimetric analysis, electrochemical techniques and DFT (density functional theory) calculations using the 6-311G+(d,p) basis set carried out in both gas and aqueous phases. This method was employed to investigate the intrinsic properties of corrosion inhibitors and their adsorption mechanisms. The findings revealed that both the molecular structure and the concentration of the SPT, significantly affect the corrosion rate of steel. The highest value of 98.78% is reached by the inhibitory efficiency of SPT at 10–2 M. Polarization curve shape suggests that SPT functions primarily as an anodic inhibitor.
