(Springer International Publishing Ag, 2021) Haldhar, Rajesh; Prasad, Dwarika; Kamboj, Divya; Kaya, Savas; Dagdag, Omar; Guo, Lei
The aerial parts extract of Momordica charantia plant were used for the corrosion resistance of carbon steel in the acidic medium (0.5 M H2SO4) utilizing weight loss method, Tafel and Electrochemical Impedance Spectroscopy. The state of mixed inhibitor adsorption on the carbon steel surface is shown by potentiodynamic polarization. M. charantia achieved the extraordinary inhibition efficiency of 93.51% at 500 mg/L of inhibitor concentration. Scanning electron microscopy and atomic force microscopy were used to know about the thin layer which was formed on the surface of carbon steel for its protection from corrosion and the adsorption of inhibitor was shown by UV-vis. spectroscopic technique. Fourier Transform Infrared Spectroscopy technique confirmed the existence of functional groups and the heteroatoms exhibit in the inhibitor. Adsorbance by the inhibitory molecules on the carbon steel surface followed the Langmuir adsorption isotherm. Hypothetical investigations (computational) showed a very valuable report. All acquired outcomes ensure that M. charantia extract can procedure an effectual preventing layer and restrict the corrosion procedure.
