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.
期刊介绍：
Protection of Metals and Physical Chemistry of Surfaces is an international peer reviewed journal that publishes articles covering all aspects of the physical chemistry of materials and interfaces in various environments. The journal covers all related problems of modern physical chemistry and materials science, including: physicochemical processes at interfaces; adsorption phenomena; complexing from molecular and supramolecular structures at the interfaces to new substances, materials and coatings; nanoscale and nanostructured materials and coatings, composed and dispersed materials; physicochemical problems of corrosion, degradation and protection; investigation methods for surface and interface systems, processes, structures, materials and coatings. No principe restrictions exist related systems, types of processes, methods of control and study. The journal welcomes conceptual, theoretical, experimental, methodological, instrumental, environmental, and all other possible studies.
