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 md/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。
Electrochemical methods such as potentiodynamic scanning, cyclic polarization and cyclic voltammetry were used to investigate the effect of 3,5-bis (2-pyridyl) -1,2,4-triazole (HBPT) In the corrosion of copper corrosion performance. Polarization curve studies showed that 3,5-di (2-pyridyl) -1,2,4-triazole inhibited copper anodic reaction in 0.5 md / L sulfuric acid solution and promoted copper cathodic reaction , Belongs to the anode type corrosion inhibitor. Cyclic voltammetry studies showed that 3,5-bis (2-pyridyl) -1,2,4-triazole may adsorb on the surface of the electrode or interact with monovalent copper, resulting in the formation of copper in 0.5 mol / L sulfuric acid solution Corrosion has played a role.
