This investigation described the inhibitive influence of Mebendazole (MBZ) on mild steel corrosion in 1M sulphuric acid. Potentiodynamic polarization and scanning electron microscopy techniques were employed. Mebendazole effectively protected mild steel in H2SO4 at 298K and 333K with maximum inhibition efficiencies of 98.02% and 99.53% respectively. The adsorption of the inhibitor on the surface of mild steel followed the mixed mode physical adsorption of Langmuir adsorption model. The corrosion rate of specimens decreased from about 47.467 mm/yr for the blank specimen to about 1.7968 mm/yr for the specimen immersed in 1M sulphuric acid containing 2.5 g/l of MBZ at 298K. However, at 333K the corrosion rates were respectively 1455 mm/yr and 6.7854 mm/yr. Scanning electron microscopy revealed that the addition of Mebendazole to the corroding system sustained a surface morphology relatively devoid of pits on the test specimens at 5 days of immersion in 2.5 g/l of inhibitor in 1M sulphuric acid.
