Abstract

The electrochemical behavior of carbon steel in saltwater saturated with CO₂ with/without an new synthesized imidazoline inhibitor was studied using polarization and electrochemical impedance spectrum (EIS), and the inhibitive ability of the inhibitor was evaluated by weight-loss method in 298-328 K temperature range. Results showed that the inhibition efficiency is up to above 80%, and imidazoline is a kind of mixed-type inhibitor. It was seen that the adsorption of imidazoline on Q235 steel can be fitted to Frumkin isotherm equation. Quantum chemistry calculation results show that the imidazoline ring and heteroatoms are the active sites of the inhibitors.
