Allium Sativum (Garlic) Extract as Nontoxic Corrosion Inhibitor
The inhibition efficiency (IE) of an aqueous extract of garlic in controlling corrosion of carbon steel in well water in the absence and presence of Zn2+ has been evaluated by mass-loss method. The formulation consisting of 2 mL of garlic extract and 25 ppm Zn2+ offers 70% inhibition efficiency to c...

| description | The inhibition efficiency (IE) of an aqueous extract of garlic in controlling corrosion of carbon steel in well water in the absence and presence of Zn2+ has been evaluated by mass-loss method. The formulation consisting of 2 mL of garlic extract and 25 ppm Zn2+ offers 70% inhibition efficiency to carbon steel immersed in well water. Polarization study reveals that this formulation controls the anodic reaction predominantly. FTIR spectra reveal that the protective film consists of Fe2+-allicin complex and Zn(OH)2. |
