Abstract

Corrosion Inhibition of Aluminium In HCL Acid Solution by Ortho Substituted Salicylidene

Author(s): S. Manivannan and G. Pabitha

Mass loss has been used to study the inhibition of aluminium corrosion in HCl solution by ortho substituted aniline-N-salicylidene. The value of inhibition efficiency obtained by the mass loss method is in good agreement and depends upon the inhibitor, the acid, period of exposure and temperature. The thermodynamic parameters for adsorption of o-substituted aniline-N-salicylidenes for the corrosion of alumimium in 1N HCl were calculated.
