(C) 2020 The Authors. Published by Elsevier B.V. This is an open access article under the CC BY-NC -ND license ( The ability of tobacco extracted from discarded cigarettes (NDC) to mitigate the corrosion of copper and zinc in artificial seawater was investigated using electrochemical, weight loss, and surface characterization methods. The PDP results revealed that NDC acts as a mixed type inhibitor with cathodic predominance. EIS measurements suggest that the increase in charge transfer resistance with increasing NDC concentration with maximum inhibition efficiency of 96.8% (copper) and 98.2% (zinc). Langmuir adsorption isotherm was found to be the best fit. A G ads reveals the mixed nature of adsorption. EFMT suggest the lower current density in presence of NDC. SECM, SEM and AFM analysis reveals the NDC film formation. UV-vis spectroscopy suggest the inhibitor/metal complex formation.
