Electrochemical assessment of imidazole derivatives as corrosion inhibitors for mild steel in 3.5 NaCl solution
The corrosion inhibition efficiency of benzimidazole, 2-methylbenzimidazole and 2- aminobenzimidazole for mild steel immersed in 3.5 NaCl solution was investigated by electrochemical impedance spectroscopy EIS at concentration range from 10-5 to 10-2 M of imidazoles and temperature range from 30 to 50°C. In addition, DC polarization was examined to determine inhibition mechanism at concentratio...
متن کاملQuantum chemical studies on adsorption of imidazole derivatives as corrosion inhibitors for mild steel in 3.5 NaCl solution
Adsorption of benzimidazole, 2-methylbenzimidazole and 2-aminobenzimidazole on mild steel in 3.5 NaCl solution was studied using density function theory DFT calculations. In this regard, charge transfer resistance Rct and double layer capacitance Cdl obtained by electrochemical impedance spectroscopy EIS were used to calculate surface coverage and to build prediction models. When prediction mod...
