ABSTRACT:
The inhibitive action of leaves extract of Azadirachta indica on Brass in Natural sea water environment was studied using mass loss measurement. The effect of temperature and immersion time on the corrosion of Brass in Natural sea water with addition of extract was also studied. The inhibition efficiency increased with increase of inhibitor concentration and decreased with rise in temperature and time. Corrosion inhibition may be due to the spontaneous physical adsorption of the plant constituents in the inhibitor on the surface of metal. The adsorption of the active molecules present in the extract on the Brass surface obeyed by the Langmuir and Temkin adsorption isotherm. The protective film formed on the metal surface was analyzed by UV and IR spectroscopy. The results indicated that the extract of Azadirachta indica leaves could serve as an effective inhibitor on Brass in Natural sea water environment.
