The inhibition efficiency and synergistic behaviour of 10-4 M Atropine methochloride was carried out using mass loss and polarisation methods in the presence of (i) metal ions, Ni2+ and Cu2+ between 10-2 M to 10-6 M concentrations, (ii) different concentrations of metal ions and 10-3 M I-, 10-3 M Cl- and 10-3 M Br- solutions and (iii) different metal ions, 10-3M I- and at three different temperatures. The analysis reveals that the inhibition efficiency of Atropine methochloride was maximum at 10-2 M in 5 hours of immersion period. Halides decreased the corrosion rate of mild steel in Sulphuric acid. The decrease is maximum with 10-3 M I-. As the temperature increased from 298K to 308K, the inhibition efficiency gradually decreased. The inhibitor was found to be effective up to 303
