Abstract

The inhibitive effect of a novel Schiff base can be evaluated by electrochemical measurements at the temperature range of 300–330 K. The inhibition efficiency of the inhibitor increases with increasing its concentration but decreases with increasing temperature. The polarisation measurement reveals that the inhibitor acts as a mixed type inhibitor. The inhibitive action of the inhibitor is attributed to the adsorption of inhibitor onto the steel surfaces, and it obeys the Langmuir adsorption isotherm model.
