dc.description.abstractInhibitive and absorptive nature of aqueous extract of palmyra palm {Borassus flabellifer Linn.) peduncle (BFP) for the corrosion of mild steel in 0.5 M H2SO4 was investigated using chemical and electrochemical techniques. Characterization of BFP was carried out using GCMS and FT-IR spectroscopic studies. The aqueous extract of BFP was found to be a good adsorption inhibitor for the corrosion of mild steel in 0.5 M H2SO4 solution at all studied temperatures and period of immersion. Thermodynamic parameters revealed that there is a strong interaction between the metal surface and inhibitor. The adsorption characteristic of the inhibitor is consistent with the assumptions of El-Awady kinetic thermodynamic and Frumkin adsorption isotherm. A comprehensive adsorption model was proposed for the adsorption of aqueous peduncle extract of Borassus flabellifer Linn, on mild steel surface. The inhibition potentials of aqueous extract of BFP was enhanced by its phytochemical constituents. The electrochemical measurement reveal that the peduncle extract behaved like mixed type inhibitor. Surface analytical techniques such as SEM and FT-IR confirmed the adsorption of BFP on mild steel surface.en_US
