Abstract: This research investigates the corrosion inhibition potential of banana pseudo-stem extract on mild steel in acidic environments. Utilizing gravimetric analysis, the study evaluates inhibition efficiency over time and with varying inhibitor concentrations. Results indicate a maximum inhibition efficiency of 97% after 24 hours with 5% v/v inhibitor concentration and 0.5 M HCl. Phytochemical analysis reveals the presence of proteins, steroids, carbohydrates, flavonoids, tannins, saponins, and glycosides in the extract, supporting its role as a green corrosion inhibitor. Adsorption of inhibitor molecules aligns with Langmuir and Freundlich adsorption isotherm models, confirmed by Gibb’s free energy values. Optimization through Response Surface Methodology predicts optimal conditions for maximum weight loss. Additionally, the study examines inhibition capacity in 0.5 M and 1.0 M HCl solutions, highlighting the extract’s efficiency in reducing corrosion rates. This research contributes valuable insights into the inhibition characteristics of banana pseudo-stem extract under specific conditions, suggesting its potential as an effective corrosion inhibitor for mild steel.
