In this research, an assessment of the influence of varying concentrations of Methyl-5-benzoyl-2-benzimidazole Carbamate (mebendazole) as an organic corrosion inhibitor for mild steel in 1.0M sulphuric acid solution was investigated. Weight loss, corrosion penetration rate, inhibition efficiency and degree of surface coverage were measured and calculated for various inhibitor concentrations and immersion time intervals. From the analysis of the results obtained, the lowest corrosion penetration

The results indicated that mebendazole is an effective corrosion inhibitor for mild steel in sulphuric acid medium.
