Convolvulus microphyllus Extract as a Green, Effective, and Affordable Corrosion Inhibitor: Theoretical Calculations and Experimental Studies

This study demonstrates the ability of Convolvulus microphyllus extract to prevent low-carbon steel corrosion (LCS) by varying inhibitor concentration. The effectiveness reaction was examined using gravimetric techniques and electrochemical procedures in a corrosive 0.5 M sulfuric acid medium. results polarization show mixed adsorption nature on LCS surface. C. microphyllus-derived film (extract) had an inhibition efficiency (IE) 92.47% at concentration 600 mg/L temperature 298 K. To examine morphology, scanning electron microscope (SEM) atomic force (AFM) were used analyze external films that protect from acid. A thin protective coat outside substrate follows Langmuir isotherm. Additionally, computational exploration provided vital insights. these experimental inhibitory outcomes are consistent with those molecular dynamic simulations.
