This study investigates the corrosion behavior of aluminum in hydrochloric acid (HCl) solutions, exploring the efficacy of zinc oxide nanoparticles and plantain peel extract as inhibitors. Through weight loss analysis, factors such as adsorption, kinetics, thermodynamics, corrosion rate, and inhibitor efficiency were examined. Optimal inhibition efficiency of 46.70% was achieved at 303K with 500 ppm inhibitor concentration in 0.5M HCl. Adsorption parameters aligned with Langmuir isotherm, indicating strong correlation (R2 ≈ 0.9999). Activation energy and free energy values suggested an endothermic reaction. Zinc oxide nanoparticles, in conjunction with plantain peel extract, exhibited effective corrosion inhibition. The study underscores the role of flavonoids, saponin, alkaloids, proteins, and tannins in facilitating bio-reduction of zinc acetate into nanoparticles. Further research avenues include exploring alternative corrosion analysis techniques and optimizing corrosion control processes.
