Abstract: The synergistic effect between tetra-butylammonium cation (TBA+) or hexadecyl pyridini-um cation (HDP+) and SCN- or I- in 0.5 mol/L H2SO4 for corrosion inhibition of iron was investigated by potentiodynamic and polarization resistance techniques.The results show that the synergistic effect between HDP+ containing π electron construction and inorganic anion is stronger than that between TBA+ and inorganic anion.It was discussed in detail that joint adsorption pattern of cation and anion on the interface of electrode-solution is related to construction and property of ions.

Key words: Inhibitor, Quaternary ammonium cation, Synergistic effect
