Abstract
Electrochemical Investigation of Manilkara zapota fruit Peel
Extract on Mild Steel in Acid Medium
A. Petchiammal
The inhibition efficacy of Manilkara zapota fruit peel (MZFP) extract on the corrosion of mild steel in 1.0N hydrochloric acid has been studied by potentiodynamic polarization and electrochemical impedance spectroscopy (EIS) measurements. The inhibition efficiency was increased with increase of inhibitor concentration and achieved maximum of more than 93% for both methods. The charge transfer resistance increased with increase of inhibitor concentration which was confirmed by impedance studies. In bode phase plot, the increasing concentration of MZFP inhibitor in hydrochloric acid solution resulted in more values of phase angle at high frequencies also suggested that, there was greater surface coverage and charge transfer resistance. The inhibitor acted as a mixed type. ie, it protected both cathodic and anodic corrosion.
