Abstract

Quinoline (QL) and its derivatives namely quinaldine (QLD) and quinaldic acid (QLDA) were tested as inhibitors for the corrosion of steel in 0.5 M HCl by weight loss method at 30 and 40 °C. Inhibition efficiency increased with increase in the concentration of of the studied compounds but decreased with increase in temperature. Results show that the order of inhibition efficiency is QLDA > QLD > QL. The adsorption of the inhibitors on the steel surface obey Langmuir and kinetic thermodynamic models.
