The inhibition effect of schiff base compounds for mild steel in HCl solution were analyzed by weight
loss method, potentiodynamic polarization, UV-vis, IR and Electrochemical impedance spectroscopy
(EIS). Potentiodynamic polarization study revealed that the schiff bases acted as mixed type inhibitors.
The EIS parameter is indicative of adsorption of schiff bases on mild steel surface leading to formation of
protective layer. The weight loss study showed that the inhibition efficiency of these compounds
increases with increase in concentration and vary with immersion time. Adsorption of schiff bases
obeyed the Langmuir adsorption isotherm. In the UV-visible and IR spectral data gave the exact structure
of the Schiff bases.
