Corrosion Inhibition Performance of Mild Steelusing L-Tryptophan with Sodium Potassium Tartrate in 0.1 M HCL

The corrosion inhibition characteristics of nitrogen containing amino acid tryptophan (250ppm)with 0.05g of SPTon mild steel in0.1M HCl, was studied by various techniques. Weight loss method analysis showed that there is an increase in inhibition efficiency by increasing the concentration of inhibitor. Polarization and impedance studies indicated that the present inhibitor system as acathodic type inhibitor. EDAX spectra confirm the presence of inhibiting elements on the metal surface and SEM analysis indicated the smoothness of the layer formed on the surface of the metal.
