Various concentration of Solanum surattense (S. surattense) aerial parts extract was utilized for low carbon steel (LCS) in the presence of corrosive medium (0.5 M sulfuric acid) utilizing weight-loss technique and electrochemical methods (Tafel and EIS). The mixed adsorption status on the LCS was exhibited by potentiodynamic polarization. S. surattense accomplished 93% corrosion inhibition effectiveness at an inhibitor concentration of 500 mg/L. SEM and AFM was utilized to distinguish the thin film framed on the outside of the metal alloy to protect it from corrosion. The molecular adhesion of the inhibitor was demonstrated to be Ultraviolet-visible (UV-Vis) spectroscopic method. The FT-IR strategy supported the existence of different functional groups and different atoms other than Carbon and Nitrogen in the protective extract. Thin layer adhesion of the inhibitor molecules outside of LCS metal substrate obeyed the Langmuir adsorption isotherm and acted as mixed type inhibitor. DFT revealed an entirely important report with high EHOMO and low ELUMO values for active phytoconstituents showing potential nature of inhibitor and good agreements with experimental outcomes. The whole acquired results entail that S. surattense creates protective coat hence limit the degree of LCS degradation. (C) 2021 Elsevier B.V. All rights reserved.
