Inhibition of N,N'-o-phenylen-bis(3-methoxysalicylidenimine) on Copper in Halide Solutions

应用恒电位稳态极化和交流阻抗技术研究了希夫碱—邻香兰素邻苯二胺 (V_oPh_V)在中性NaCl或NaBr溶液中对金属铜阳极溶解和腐蚀的缓蚀作用 .通过比较铜在空白溶液与含有V_o_Ph_V溶液中的电化学行为解释了V_o_Ph_V的缓蚀机制 .此外还研究了V_o_Ph_V自组装膜在Na Cl溶液中对铜腐蚀的缓蚀效应 .Inhibition of N,N'_o_phenylen_bis(3_methoxysalicylidenimine)(V_o_Ph_V)on corrosion and anodic disslution of copper in neutral NaCl and NaBr solutions was investigated in terms of potentiostatic steady_state polarization and A.C. impedance techniques.The inhibition mechanism of V_o_Ph_V to copper corrosion was interpreted in detail by comparing the electrochemical behaviors of copper in halide solutions with or without V_o_Ph_V. Besides,the inhibition effect of self_assembled V_o_Ph_V film on copper corrosion in NaCl was also studied.作者联系地址：山东大学化学学院!山东济南25100,山东大学化学学院!山东济南25100,山东大学化学学院!山东济南25100,山东大学化学学院!山东济南25100,山东大学化学学院!山东济南25100Author's Address: College of Chemistry,Shandong University,Jinan 250100 Chin
