Green corrosion inhibitor for steel in acid medium

摘要

Phoenix dactyliferasQQd is subjected to corrosion evaluation by the following methods • Weight loss - reveals nearly centum percentage inhibition efficiency at 30°C. - even at 50°C, the metal is protected appreciably. • Free energy and enthalpy values correspond to spontaneous adsorption of the inhibitor and protection of the metal. • The electrochemical investigations indicate the mixed mode of inhibition and the mechanism of inhibition is through adsorption. • The adsorption is due to the lone pair of electrons present in the hetero atoms of the P. dactyliferawhich is validated from IR spectral studies. • The SEM photographs bring to light the protective nature of steel by inhibitor. • The results suggest that the seed of/", dactylifera is an effective corrosion inhibitor, which can be substituted for synthetic inhibitor for better performance and environmental protection.
