Investigation of Corrosion Inhibition of Mild Steel in 0.5 M HSO with Inhibitor Extracted from Rotten Grapefruits (): Adsorption, Thermodynamic, Electrochemical, and Quantum Chemical Studies.

Corrosion inhibition of mild steel (MS) was studied using isolate in 0.5 M HSO, which was isolated from rotten grapes () via biofilm formation. Biofilm over the MS surface was asserted by employing FT-IR and FE-SEM with EDXS, electrochemical impedance spectroscopy (EIS), AFM, and DFT-ESP techniques.
