Anticorrosive property of a gemini cationic surfactant (12-4-12) and its monomeric counterpart, dodecyl trimethyl ammonium bromide (DTAB), on mild steel in 1M hydrochloric acid solution was investigated by electrochemical impedance spectroscopy (EIS). The results revealed the corrosion inhibition effect of these two surfactants on mild steel in acidic solution. It was observed that by increasing the immersion time in test solutions, corrosion resistance of mild steel increased, reaching a constant value after 2 h and 4 h immersions for 12-4-12 and DTAB, respectively. The monomeric surfactant, DTAB, had better corrosion inhibition effect compared to 12-4-12. The lower performance of 12-4-12 could be related to steric hindrance of the free head group.
