Mild Steel Corrosion Inhibition by Daucus carota Pulp Extract in 1N Hydrochloric Acid Medium

Authors(2) :-V. Kavitha, Dr. N. Gunavathy

Daucus carota pulp extracts (DCP) was investigated as corrosion inhibitor of mild steel in 1N HCl using phytochemical screening, HPLC analysis, conventional weight loss measurement with immersion time, temperature studies, and surface morphological examination. Phytochemical screening and HPLC analysis proved that protective layer was contributed by bioactive constituents DCP extract. Inhibition efficiency increased with increase in concentration of inhibitor from 0.05% to 2.0% v/v. Maximum inhibition efficiency of 95.34% was obtained for DCP extract in 1N HCl for an immersion period of 5h.  Scanning electron microscopy (SEM) and energy dispersive X-ray (EDX) techniques were employed for surface examination of uninhibited and inhibited mild steel. These studies provided evidence of improved surface condition on mild steel, due to adsorption of DCP phytonutrients for corrosion protection
