Influence of succinic acid on the corrosion inhibition of Sodium metavanadate in chloride medium
Journal Title: International Journal of Advances in Engineering, Science and Technology - Year 2011, Vol 1, Issue 1
Abstract
The inhibition efficiency (SMV) – succinic acid system is controlling corrosion of carbon steel in an aqueous solution containing 60 ppm of Cl- has been evaluated by weight loss method.250 ppm of SMV has 56% of IE. Addition of succinic acid to SMV improves the inhibition efficiency of the system. Formulation consisting of 250 ppm of SMV and 250 ppm of succinic acid has 97% IE. Synergistic effects exist between SMV and succinic acid, if the synergism parameters are greater than 1. Mechanistic aspects of corrosion inhibition have been studied by electro chemical studies like polarization and electro chemical impedance spectroscopy. FTIR spectra reveals that the protective film consists of Fe2+ - SMV complex and Fe2+ -succinic acid complex, the protective film has been analyzed by fluorescence spectra, SEM and AFM .
