Plant extracts as “green” corrosion inhibitors for steel in sulphuric acid

Abstract

In recent years, plant extracts have become the focus of corrosion inhibitor research due to their low toxicity, easy availability and economical preparation. This review presents most of the recent contributions made to the application of plant extracts as corrosion inhibitors for steel in sulphuric acid, as well as in both hydrochloric acid and sulphuric acid. The constituents, properties, adsorption modes and inhibition mechanisms of these natural products are discussed. Evaluation methods and the factors that influence the corrosion-inhibition efficiency of plant extracts are also summarised.
