KUMAR, SUDESH et al. SYNERGISTIC EFFECT OF CALOTROPIS PLANT IN CONTROLLING CORROSION OF MILD STEEL IN BASIC SOLUTION. J. Chil. Chem. Soc. [online]. 2009, vol.54, n.1, pp. 83-88. ISSN 0717-9707. doi: 10.4067/S0717-97072009000100020.
The alcoholic extracts of leaves, latex and fruit from the Calotropis procera and Calotropis gigantea are tested for corrosion inhibition in basic solution by mass loss method and thermometric method. In the present investigation the extract reduces the corrosion rate of mild steel in basic solution. The inhibition efficiency increases as the extract concentration is increased. The alcoholic extract of Calotropis is found effective corrosion inhibitor in basic media and give up to 80.89% efficiency.
