Eco friendly corrosion Inhibitors: A review

Abstract

In the past few decades significant concern has arisen over the use of synthetic compounds as corrosion inhibitors due to their environmental consequences. Hence a great deal of work has been initiated towards the exploration of applicability of extracts of natural substances to prevent the corrosion of various metals. Extracts of natural products being biodegradable are eco-friendly and pose no threat to the environment. Various researchers have successfully demonstrated the applicability of extracts of natural products as green corrosion inhibitors. This manuscript states a detailed account of the work performed in view of the above. Natural substances like extracts of plant leaves, steam, seed, fruit, and essential oils can be used as efficient corrosion inhibitors on metal surfaces
