Abstract: Influence of electron releasing groups in benzylidene thiocarbohydrazide and their synergetic effect with iodide ions on acidizing corrosion inhibition of carbon steel in 15% HCl using chemical and electrochemical methods has been studied. Tafel polarization measurements indicate that these compounds act as mixed-type inhibitors. The adsorption of these compounds obey Langmuir adsorption isotherm and the thermodynamic parameters are also calculated to explain their inhibitive action. The increase in synergism parameter (Sθ) indicates that the inhibition efficiency is improved in the presence of the iodide ions. Further, the density functional theory is used to validate the experimental results.
