摘要: 采用失重法、电化学测试以及量子化学计算方法研究6-硝基苯并咪唑在KOH(0.1mol/L)溶液中对Zn的缓蚀性能。结果表明，6-硝基苯并咪唑能有效抑制锌的阳极氧化，从而抑制Zn在碱液中的自腐蚀，属于阳极型缓蚀剂；当6-硝基苯并咪唑浓度为5mmol/L时缓蚀效果最佳，其效率达到96.8%；6-硝基苯并咪唑在锌表面的吸附符合Langmuir等温式。

关键词 ：缓蚀剂, 锌, 6-硝基苯并咪唑, 吸附

Abstract：The effect of 6-nitrobenzimidazole on the zinc corrosion in 0.1 mol/L KOH solution has been studied by electrochemical, weight loss measurements and quantum chemical calculations. It has been shown that 6-nitrobenzimidazole act as an anodic inhibitor, can effectively restrain the process of the anodic oxidation of zinc. The highest value of inhibition efficiency is 96.8% at 5 mmol/L concentration. Thermodynamic calculation suggests that the adsorption of 6-nitrobenzimidazole follows Langmuir adsorption isotherm.

Key words： inhibition zinc 6-nitrobenzimidazole adsorption
