摘要:The adsorption and inhibition effects of fruit extracts of Citrus aurantium (CAU), Moringa oleifera(MOL) and Capsicum annuum (CAN) on corrosion of copper were studied in nitric acid medium. Gravimetric,potentiodynamic polarization and electrochemical impedance spectroscopic techniques were used to evaluate theinhibition efficiency. Electrochemical analysis indicated that these fruit extracts acted as predominantly cathodic mixedinhibitors. The adsorption of fruit extracts on the copper surface, leading to inhibition of corrosion process, followedLangmuir adsorption isotherm.
