Abstract

The corrosion inhibitory properties on copper in acidic media by anisalidine derivatives viz. N-(4-nitro phenyl) p-anisalidine (SB1), N-(4-chloro phenyl) p-anisalidine (SB2), N-(4-phenyl) p-anisalidine (SB3), N-(4-methoxy phenyl) p-anisalidine (SB4), N-(4-hydroxy phenyl) p-anisalidine (SB5) have been studied using mass loss method, Langmuir adsorption isotherm and surface analysis by Atomic Force Microscopy (AFM). The inhibition efficiency increases up to 98.99% with increasing additive concentration it may be due to adsorption of the additive molecules on the copper surface.
