EIS results indicate that thestudied compound inhibit the acid corrosion by adsorption mechanism. Potentiodynamicpolarization measurement suggest that the inhibitor system act as a mixed type by affectingboth anodic and cathodictafel slopes during the acid corrosion of both the studied medium.Quantum chemical studies are in accordance with the experimental values.enMild steelacid CorrosionPregabalinEISDFTBook
