| Abstract: | Extracts of Ricinus communis leaves were tested for corrosion inhibitory
effects towards mild steel in 100 ppm sodium chloride solution. The
anticorrosion efficiency of plant extracts was studied by means of weight loss,
electrochemical polarization and impedance measurements. It was found from
weight loss measurements that the corrosion inhibition efficiency was about 84%
in 300 ppm of the plant extract. Polarization measurements indicated that the
plant extract acted as anodic inhibitor. Electrochemical impedance results also
showed that the plant extract increased the corrosion resistance of mild steel
and the formations of iron-organic complex reduced the corrosion of mild steel
in neutral system. |
