Citrus Peel As An Eco-Friendly Corrosion Inhibitor

Abstract

Corrosion presents a substantial industrial challenge, resulting in considerable economic losses, environmental risks, and safety issues. Conventional corrosion inhibitors, typically formulated with hazardous substances, present significant threats to human health and the environment. This research examines the efficacy of citrus peel extract as a sustainable corrosion inhibitor for mild steel in 0.5M H₂SO₄. Citrus peels possess bioactive compounds, including flavonoids, that can adhere to metal surfaces, creating a protective barrier that diminishes corrosion rates. The findings indicate that citrus peel extract is a cost-effective and sustainable substitute for synthetic corrosion inhibitors, thereby advancing green chemistry and industrial sustainability.
