Inhibition Performance of Biochar extract of Manihot esculenta tuber peel for Corrosion Inhibition of mild steel in Hydrochloric acid solution

Abstract: The weight loss (gravimetric method) and potentiodynamic polarization (electrochemical method) techniques were used to measure the corrosion rates of mild steel in 1 M HCl in the presence of char extract made from Manihot esculenta peel (MECE) as an inhibitor. The outcome demonstrated that extract has inhibitory effects at all temperatures. Adsorption is the mechanism of inhibition, and the Langmuir isotherm best fits the data. Potentiodynamic polarization and electrochemical impedance were used to calculate the activation energies, enthalpies, entropies, and entropies of the dissolution process as well as the free energies for the adsorption process. Important data regarding the inhibitory behavior of the char extract of Manihot esculenta peel was gathered using the basic thermodynamic functions.
