| 摘 要： | 利用动电位扫描、循环极化、循环伏安等电化学方法研究了3,5-二(2-吡啶基)-1,2,4-三唑(HBPT)在0.5 mol/L H2SO4介质中对铜的缓蚀性能.极化曲线研究表明3,5-二(2-吡啶基)-1,2,4-三唑在0.5 mol/L硫酸溶液中对铜的阳极反应起抑制作用,对铜的阴极反应起促进作用,属于阳极型缓蚀剂.循环伏安研究显示3,5-二(2-吡啶基)-1,2,4-三唑可能在电极表面产生吸附或与一价铜发生作用,从而在0.5 mol/L硫酸溶液中对铜起到缓蚀作用.

| Abstract: | The efficiency of 3, 5-bis(2-pyridyl)-1, 2, 4-triazole (HBFT)as copper corrosion inhibitor in 0.5 mol/L H2SO4 solution was studied by electrochemical polarization, cyclic polarization, and cyclic voltammetry methods. Polarization measurements showed that HBPT can inhibit the anodic reactions of the copper in 0.5 mol/L H2SO4 and accelerate the cathodal reactions and act as a kind oi anodic inhibitor. Cyclic voltammorgam measurements indicate 3,5-bis(2-pyridyl)-1 ,2,4-triazole may adsorb on the surface of copper or interact with Cu+ , thus inhibiting the corrosion of copper in 0.5 mol/L H2SO4 . |
