An Exploration about the Interaction of Mild Steelwith Hydrochloric Acid in the Presence of N ‑(Benzo[ d ]thiazole-2-yl)-1-phenylethan-1-imines

Cost effective inhibition of mild steel corrosion employing eco-friendly materials is a high priority subject for the industries, these days. Therefore, in this work, a series of N-(benzo[d]thiazole-2-yl)-1-phenylethan-1-imines(BTPEI, BTCPEI, BTTEI and, BTPIA)for mild steel protection in 1 M HCl were explored by adopting methods like gravimetric, adsorption isotherms, and the electrochemical methods, for example, electrochemical impedance spectroscopy (EIS) and potentiodynamic polarisation. Different spectral characterization such as FTIR and 1H NMR were used to confirm the synthesized derivatives. The experimental results affirmed that all the inhibitors are proven to be very efficient for combating corrosion for mild steel in acidic media. The determined thermodynamic and activation parameters were used to provide a further understanding of the mechanism of inhibitive activity. The computed Gibbs free energy values suggested strong chemical interaction of inhibitors with the mild steel surface, thereby ...
