摘要：

A new Schiff base compound named 4-(4'-benzoylhydrazine)-pyridinecarboxaldehyde hydrazone (BPBH) was synthesized and investigated as a corrosion inhibitor for mild steel in 1 M HCl using weight loss measurements, electrochemical techniques, and adsorption studies. The structure of BPBH was characterized by elemental analysis, infrared spectroscopy (IR), and H-1 nuclear magnetic resonance (NMR). The results clearly suggest that the compound acts as a mixed-type inhibitor of acid corrosion of mild steel. The adsorption of BPBH on the metal surface in 1 M HCl was found to agree with the Langmuir isotherm with a standard free energy of adsorption () of -31.60 kJ/mol. Scanning electron microscopy images indicate that BPBH exhibits good corrosion inhibition performance for mild steel in 1 M HCl. Quantum chemical calculations were also carried out to verify the inhibition efficiencies obtained from all the experiments.
