| Abstract | ||||
| Corrosion inhibition of two Schiff base complexes were examined for mild steel in 1M HCl solution. These two Schiff base complexes, Cd(II) and UO2(II) were synthesized through the reaction of CdCl2.H2O and UO2(NO3)2.6H2O with the Schiff base ligand N-carbamimidoyl-4-((4-chlorobenzylidene) - amino) benzenesulfonamide in ethanol. The corrosion behavior was studied for the mild steel by weight loss method, Open circuit potential measurements (OCP), Potentiodynamic polarization (Tafel polarization), and Electrochemical impedance spectroscopy (EIS). The compounds have a promising corrosion inhibition materials for the mild steel in the investigated acid medium. | ||||
