In this study, the corrosion inhibitory activity of symmetrical bis(imino)pyridine (BIP-16) was tested by the Linear Polarization Resistance (LPR) and Electrochemical Impendence Spectroscopy (EIS) methods on zinc and iron. The investigation was carried out in a neutral and acidic medium of 0.5 M NaCI solution. The temperature-dependent (25-45 °C) inhibitory efficacy of BIP-16 on iron and zinc was tested in an acidic medium (pH 3). Under the same conditions, the time dependence of BIP-16 up to 72 h was examined . Moreover, a synergistic effect of BIP-16 with cerium acetate was also examined in time and temperature (25-45 °C) dependence on zinc (pH 7) and iron (pH 3) in 0.5 M NaCI solution at optimal concentrations. The inhibition efficiency of BIP-16 declined with time on both zinc and iron indicating physisorption. Also, kinetic and thermodynamic parameters of this process were calculated. To gain deeper insights into the inhibitory mechanism of tested compounds, DFT calculations were ...performed.
