An aqueous extract of plant material Henna (Lawsonia Inermis L) powder has been used as a corrosion inhibitor in controlling corrosion of carbon steel immersed in an aqueous solution containing 60 ppm of Cl-, by the mass loss method, in the absence and presence of Zn2+. The main constituent of this plant extract is Lawsone. It has excellent inhibition efficiency (IE) and shows excellent IE at pH 6, 8 and 12. In the presence of Zn2+ there exists a synergistic effect. Synergism parameters have been calculated to evaluate the synergistic effect. Analysis of variance (F-test) reveals that the synergistic effect existing between henna extract and Zn2+ in statistically significant. The protective film has been analyzed using Fourier transform infrared (FTIR) spectroscopy. The film consists of Fe2+ - Lawsone complex and Zinc hydroxide [Zn (OH)2]. It is found to be UV-fluorescent. Electro chemical studies such as potentiodynamic polarization and alternating current (AC) impedance have been used to find the mechanistic aspects of corrosion inhibition.
