Abstract

Synergistic effect of Zn2+ ion and 2-Carboxyethyl phosphonic acid (2-CEPA) on the corrosion inhibition of mild steel in water containing low concentration (60 ppm) of chloride ion has been evaluated by weightloss and potentiostatic polarisation methods. The results show that 96% inhibition efficiency is achieved with binary system consisting of 100 ppm Zn2+ and 100 ppm 2-CEPA. The mechanistic aspects of corrosion inhibition and the nature of the film formed omn the metal surface have been analysed with the help of x-ray diffraction (XRD) technique, UV-Vis-NIR spectra and luminescence spectra.
