Abstract
Maltodextrin (MLD), a biopolymer was introduced as a novel green inhibitor to mitigate the corrosion of zinc in sulfamic acid medium by weight loss and by electrochemical methods. Conditions were optimized to obtain maximum inhibition efficiency. Thermodynamic parameters were evaluated. The surface morphology was studied by SEM, EDX, AFM analysis. Adsorption of inhibitor was re-affirmed by FT-IR spectroscopy, Atomic absorption spectroscopy (AAS), Raman spectroscopy and powder X-ray diffraction (XRD) analysis. Maximum efficiency of 72% was observed for the addition of 400 ppm of MLD. Surface morphology and spectroscopic studies confirmed the adsorption of MLD onto the surface of zinc. Results obtained by classical and electrochemical methods are in good agreement with one another. Maltodextrin emerged as an effective eco -friendly green inhibitor.
