The Action Mechanisms of BIMGCS12-3 as Corrosion Inhibitor of Mild Steel for Vitriolic Acid Pickling
Propanediyl-α, ω-bis-(N-dodecyl benzimidazole ammonium bromide), (abbreviated as BIMGCS12-3), was tested as inhibitor for the corrosion of mild steel in 1M H2SO4. It was found by weight loss technique that prepared inhibitor adsorbed on mild steel surface forming a protecting film. Polarization curves show that BIMGCS12-3 acts as mixed type inhibitor. Moreover, surface morphological examination has been carried out by SEM.
