Corrosion prevention studies show a predominant trend in the recent era. Especially mild steel material was used in many industrial sectors because it has specific properties like malleability and ductility. Corrosion inhibition action of a novel synthesized N-(1,3-benzothiazol-2-yl)-2-[4-furan-2-carbonyl)piperazin-2-yl]acetamide (1,3BFCPA) compound was performed on MS-mild steel material in 1 N HCl and 1 N H2SO4 medium. Using the mass loss data, the inhibitor efficiency has been evaluated on both the acidic and alkaline mediums. The inhibitor shows a maximum inhibitor efficiency on both acidic mediums, but when comparing 1N sulfuric acid, it shows a better efficiency of 90%. Based on surface coverage analysis (ϴ) from mass loss data, adsorption isotherms were interpreted to fit the behavior of the inhibitor over the surface of MS material, which shows a Langmuir adsorption isotherm.
