摘　　要：采用失重法、电化学方法研究新型三唑衍生物在1 mol/L H2SO4中缓蚀性能和机理,并研究该缓蚀剂在20g钢表面的吸附行为。结果表明,新型三唑缓蚀剂是一种混合型缓蚀剂,在1 mol/L H2SO4溶液中缓蚀剂浓度为1 000 g/L时缓蚀率最高,为94.6%。Matlab拟合表明该缓蚀剂在20g钢表面的吸附行为符合Bockris-Swinkels吸附等温式。The inhibitive effect of new synthetical triazole derivative was evaluated in 1 mol/L HzSO4 using weight-loss, electrochemical methode. The adsorption of triazole derivative on 20g steel surface was studied by weight-loss. The results showed that the triazole derivative is a mixed-type inhibitor, the highest inhibition efficiency is up to 94.6% at the concentration of 1 000 g/L inhibitor. It was found that the adsorption of triazole derivative on 20G steel can be fitted to Bockris-Swinkels isotherm equation.
