N2 - Chemically, chitosan is a linear polysaccharide constituted of arbitrarily distributed D-glucosamine and N-acetyl-D-glucosamine constituents combined together via β-1,4-glycosidic linkage. Because of increasing ecological awareness and strict environmental regulations, species of natural and biological origin such as chitosan can be identified as ideal environmental sustainable alternative to replace traditional heterocyclic (toxic) corrosion inhibitors. Although, chitosan contains numerous electron rich sites however chitosan itself is not highly effective aqueous phase corrosion inhibitors. Aqueous phase application of chitosan is limited because of its limited solubility. However, chemically modified chitosan derivatives, such as chitosan based Schiff bases (CSBs) exhibit remarkable solubility in such electrolytes. Therefore, recently various reports dealing with the anticorrosion potential of CSBs have been reported. Present review article describes the collections on CSBs as aqueous phase corrosion inhibitors. Nature of CSBs adsorption through chelation (coordination) has also been discussed based on literature outcomes.
