Abstract
This work aims to be a contribution in the field of corrosion control and proposes to study the effect of molar hydrochloric acid on mild steel (MS) in the presence and in the absence of 11-(Bis((1H-pyrazol-1-yl)methyl)amino)undecanoic acid(L4), employing the gravimetric method and stationary (PDP) and transient electrochemical (EIS) techniques. In addition to the experimental measurements employed in our study, DFT and molecular dynamic simulation (MDS) were employed. The inhibitory performance of this compound increases with its concentration as well as the temperature of the aggressive medium to reach a value of 99.5% at at 10−3 M and at the temperature 308 K. It can be found that L4 is a mixed-type corrosion inhibitor predominantly anodic. The thermodynamic study has shown that its adsorption is chemical in nature and follows the Langmuir isotherm model. The DFT and MD results are correlating with the experimentally obtained results.
