The inhibition efficiencies of inhibitor systems constituting various combinations of o-nitrophenol (ONP) and zinc ions in controlling corrosion of carbon steel immersed in ground water for seven days had been evaluated by weight loss method. The nature of the protective film formed on the metal surface has been analysed by FTIR spectra. The protective film was found to consist of Fe2+ - ONP complex. Synergism parameters and Analysis of variance (ANOVA) had been used to evaluate the synergistic effect existing between various inhibitors.
