“Green guardians: A comprehensive review of environmentally friendly corrosion inhibitors from plant extract to ionic-liquids in industrial applications”

Abstract

Corrosion presents a major threat to materials, economic stability, and environmental health, and requires the creation of effective and sustainable solutions. The rise of eco-friendly corrosion inhibitors is discussed in this review, with highlighting their ability to reduce corrosion while minimizing environmental impact. We discuss a variety of inhibitors, including biopolymers, plant extract, bio-surfactants, synthetic polymers, and ionic liquids, and their effectiveness in different industrial applications. The transition from traditional synthetic inhibitors to natural alternatives, particularly plant extracts, signifies a growing commitment to sustainability. These green inhibitors are noted for their affordability, biodegradability, and safety, offering a promising alternative to conventional corrosive agents. The review also addresses challenges such as limited solubility and performance variability, while showcasing recent advancements in formulation and synthesis. By synthesizing current research and identifying future directions, this article emphasizes the importance of eco-friendly corrosion inhibitors in promoting safer industrial practices and protecting the environment. The findings advocate for a shift towards sustainable corrosion management, paving the way for innovative solutions that meet global environmental standards.
