    Abstract

    The inhibition efficiency (IE) of Polyacrylamide (PAA) in controlling corrosion of carbon steel in ground water in the absence and presence of Zn2+ has been evaluated by weight loss method. The formulation consisting of 250 ppm PAA and 50 ppm Zn2+ has 98% IE. It is found that the inhibition efficiency (IE) of PAA increases by the addition of Zn2+ ion. A synergistic effect exists between PAA and Zn2+. The mechanistic aspects of corrosion inhibition have been studied using polarization study. Also FTIR spectra reveal that the protective film consists of Fe2+ − PAA complex and Zn (OH)2. The scanning electron microscopy (SEM) study confirms the protection of carbon steel surface by strong adsorption of PAA. A suitable mechanism for corrosion inhibition is proposed based on the results from the above studies.
