ZAAFARANY, I.. Phenyl Phthalimide as Corrosion Inhibitor for Corrosion of C-Steel in Sulphuric Acid Solution. []. , 27, 5, pp.631-643. ISSN 0872-1904.

The effect of some phenyl phthalimide derivatives on the corrosion of carbon steel in 0.5 M H₂SO₄ solution was studied using weight loss and galvanostatic polarization techniques. The percentage inhibition efficiency was found to increase with increasing concentration of inhibitor and with decreasing temperature. Inhibition was explained by adsorption of these compounds on the metal surface. The adsorption follows Freundlich adsorption isotherms. Some thermodynamic functions were computed and discussed.
