Comparative Study of Amoxicillin and Sulphadoxine as Corrosion Inhibition Behaviour on Mild Steel in 1M Sulfuric Acid Medium

The corrosion study of mild steel in 1 M sulfuric acid solution has been done in absence and in presence of inhibitors- Amoxicillin and Sulphadoxine in 1M sulfuric acid solution. The comparative study of corrosion inhibition tendencies of these inhibitors reveals, Amoxicillin is better inhibitor than Sulphadoxine. The corrosion study of mild steel in 1M sulfuric acid solution in absence and in presence of these inhibitors have been done by Weight loss, Potentiodynamic polarization and Open Circuit potential techniques. The result hold mutually in good agreement with these techniques. The surface analysis has been done by Scanning Electron Microscopic Analysis is in accordance to the result obtained by above mentioned techniques. It also obeys the Langmuir adsorption isotherm.
