Abstract
Abstract The anti-corrosion behavior of biopolymers “sodium alginate (SA) and chitosan compound (CC)” on copper in the 1 M hydrochloric medium was carried out using polarization curves and electrochemical impedance spectroscopy measurements. The obtained results show that the inhibition increases with biopolymers concentration. To better understand the adsorption mechanism, describing the relationship between inhibitory ability and the molecular structure of biopolymers, quantum chemical and Monte Carlo simulation approaches were performed.
