The Effectiveness of Musa Paradisiaca as Green Inhibitor for Mild steel in Marine Corrosion

Abstract

Corrosion is characterized as metal and alloy degradation or destruction due to a chemical or electrochemical response to the surrounding environment or medium. Different metals corrode at different rates. Many organic and inorganic compounds have been investigated in the control of corrosion by adding the corrosive fluids as they are readily accessible, inexpensive, sustainable and environmental friendly. This research evaluates the effectiveness of Musa paradisiacal as an organic inhibitor of mild steel in marine corrosion. The gravimetric and linear polarization methods were applied to study the corrosion behaviour of mild steel. All the parameters analysed showed good inhibitory characteristics against the corrosion of mild steel in solution being tested, and their efficiency was found to increase with the inhibitor concentration. After a varied immersion duration, the gravimetric and electrochemical measurements for mild steel in seawater showed that the presence of Musa paradisiacal significantly reduces the corrosion densities (icorr) of 0.44 X 10-6 Acm-2 and corrosion rates of 0.00507 mm/year, as the polarization resistance (Rp) of 2536.6 and inhibition efficiency (IE) of 99.38 % are synchronously increased.
