文摘
The synthesized imines are good inhibitors for the corrosion of 15% HCl. Schiff base compounds were found to be mixed-type inhibitors. The adsorption of the inhibitors on steel surface obeyed Langmuir isotherm. The SEM and EDX analyses support the polarization and EIS data. Excellent correlation exists between inhibition efficiency and quantum chemical parameters.
