This research work is concerned with the development of new ecofriendly inhibitor system which functions efficiently as green inhibitor for the corrosion control of carbon steel in aqueous environment. The inhibition efficiency of corrosion of carbon steel in neutral, aqueous environment containing 180 ppm of Cl- ions in DD water by leaf extract of plant Syzygium Jambos (SJLE) which contains active constituents1 that exhibit synergistic property with Mn2+ ions has been investigated. A film is formed on the surface of the carbon steel immersed in the inhibitor system containing the extracts of the plant Syzygium Jambos and Mn2+ ions. In order to investigate the nature of the protective film, UV-visible spectroscopy, scanning electron microscopy, FTIR spectroscopy and electrochemical studies have been used in the present study. Polarisation techniques have been used to determine the nature of inhibitor. Based on the results obtained from the mass-loss method, polarisaion studies, surface analysis, UV, FTIR, electrochemical studies, a suitable mechanism for the corrosion inhibition has been proposed.
