Abstract
The soxhlet extraction method was used to prepare the extract of Cinnamoum tamala (C. tamala). Corrosion resistance performance of C. tamala leaves extract for low carbon steel (LCS) in the solution of 0.5 M H(2)SO4 was examined by Eletrochemical impedance spectroscopy (EIS), Tafel and gravimetric loss studies. Notably, C. tamala showed much high 96.76% industrial required efficiency at very low 100 mg/L critical concentration. Theoretical studies, using UV-vis, Density functional theory (DFT) and molecular dynamics (MD) simulation, were led as a valuable report for understanding the electronic adsorption, comparative inhibitory activities of phytochemicals. The results obtained revealed that C. tamala extract might be used as a highly efficient industrial required corrosion inhibitor. (C) 2021 Elsevier B.V. All rights reserved.
