Plant Extracts as Green Corrosion Inhibitors

Abstract

Plants and plant-based products are considered green, and their application for various purposes is in agreement with the provisos of environmental sustainability. Several reports and review articles are available in the literature on the application of plant extracts as corrosion inhibitors. This chapter presents a glimpse of the utilization of natural extracts of plants as corrosion inhibitors. The significance of plant extracts in inhibition, with some literary examples, is provided. The major phytochemicals responsible for corrosion protection are outlined. Some of the major parameters in extract preparation are discussed. Very briefly, some of the issues in the practical utility of extracts in commercialization as corrosion inhibitors are discussed.
