| 摘 要： | 在酸性介质中,季铵阳离子与无机阴离子对铁具有明显的缓蚀协同效应,阴离子的表面活性越强,对协同效应的贡献越大,阳离子的结构对协同效应同样有着明显的影响。本文采用电化学方法仔细地研究了硫酸溶液中四丁基铵阳离子(TBA~+)和十六烷基吡啶阳离子(HDP~+)与SCN~-及I~-对铁的缓蚀协同效应。

| 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. |
