Abstract

The corrosion inhibition of aqueous extract of C. Papaya leaves on mild steel in 60 ppm Cl ion containing aqueous medium was studied by using inhibition efficiency and degree of surface coverage. The most suitable inhibitor concentration was found to be 2 ml of C. Papaya leave extract with inhibition efficiency (IE) of 91% at Zn2+ (50 ppm) by the weight loss method.Synergism parameters have been calculated to evaluate the synergistic effect existing between C. Papaya leave extract and Zn2+. The influence of immersion time and P+ has also been investigated. The protective film has been analyzed using Fourier transform infrared (FTIR) spectroscopy.
