Abstract

The formulation consisting of 50ppm polyacrylamide (PAA), 300ppm phenyl phosphonic acid (PPA) and 50ppm Zn2+ has 95 percent inhibition efficiency in controlling corrosion of mild steel in a neutral aqueous environment, containing 60ppm Cl-, a situation commonly encountered in cooling water systems. A discussion of mechanistic aspects of corrosion inhibition is based on the results obtained from a potentiostatic polarization study, UV-visible, FTIR and luminescence spectra. The protective film is found to be luminescent and to consist of Fe2+ - PAA complex, Fe2+ - PPA complex and Zn(OH)2
