E.M. Mabrouk ,, S. Eid , M.M. Attia
Corrosion inhibition effect of Azo dye compound based on chromotropic acid has been studied on carbon steel corrosion in
0.5M sulfuric acid solution using potentiodynamic polarization and weight loss techniques. The result showed that the
studied azo dye is good corrosion inhibitor. The inhibition efficiency of the studied azo dye increases with increase in
concentration, and decreases with increase in temperature. The morphology of the surface and the adsorption isotherm were
studied. The values of thermodynamic parameters were computed and expounded.
