In this study, the inhibition effect of BESB6 Schiff base on carbon steelX52
corrosion in 0.5 M HCl solution was studied. For this aim, electrochemical
techniques such as potentiodynamic polarization curves, weight loss (WL) were
used. It was shown that, the BESB6 schiff base has remarkable inhibition efficiency
on the corrosion of carbon steel in 0.5 M HCl solution. Polarization measurements
indicated that, the studied inhibitor acts as mixed type corrosion inhibitor with
predominantly control of cathodic reaction. The inhibition efficiency depends on the
concentration of inhibitor and reaches 95% at.001M BESB6. The remarkable
inhibition efficiency of BESB6 was discussed in terms of blocking of electrode
surface by adsorption of inhibitor molecules through active centers. The adsorption
of BESB6 molecules on the carbon steel surface obeys Langmuir adsorption
isotherm.
