Use of Trochodendron Aralioides Extract as Green Corrosion Inhibitor for Mild Steel in 1M HCl Solutions

Recently, there is an interesting discussion that has transpired around the world about usage of plant extracts as corrosion inhibitors. We report to control in mild steel (MS) specimens a 1M HCl medium, Trochodendron aralioides (T. aralioides) extract was used economical green inhibitor. The various tests, namely, potentiodynamic polarization, weight loss measurements and electrochemical impedance spectroscopy (EIS) were performed analyze inhibition efficiency (IE) extract. highest IE value 96.42% seen at 250 ppm, with IE% increasing concentration increased. Potentiodynamic polarization suggests T. acts mixed-type UV–visible (UV–Vis) FT-IR inhibitor study adsorption mechanism surface analysis specimen, respectively. results revealed form protective film on specimens, thereby reducing corrosion. Surface morphological studies such AFM, EDX SEM tests presence absence being analyzed by observing metal.
