新型三唑衍生物缓蚀剂在HCl中的缓蚀性能

INHIBITION AND THERMODYNAMICS OF NEW TRIAZOLE DERIVATIVE IN 1 mol/L HCl SOLUTION

用失重法、电化学方法研究新型三唑衍生物在1 mol/L HCl中缓蚀性能以及在Q235-A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/LHCl溶液中最高缓蚀率达到95%以上,在Q235-A钢表面的吸附行为符合Langmuir吸附等温式,且吸附为吸热反应。

The inhibitive effect of new synthetical triazole derivative was evaluated in 1 mol/L HCI using massloss,electrochemical methode. The adsorption of triazole derivative on Q235-A steel surface was studied by mass-loss. The results showed that the triazole derivative is a mixed-type inhibitor, the highest inhibition efficiency is up to 95%. It was found that the adsorption of triazole derivative on Q235-A steel can be fitted to Langmuir isotherm equation, and the adsorption is endothermic reaction.
