摘　　要：本文用恒电位、恒电流、循环扫描等电化学方法,首次制备了邻菲啉(O-phen)聚合膜修饰电极.在0.01mol/L KClO_4水溶液中,其氧化与还原过程的峰电位分别为+0.04V和-0.53V(vs.SCE).该修饰电极在酸性、中性、碱性条件下均具有良好的稳定性.能较好地改善K_3Fe(CN)_6和V_(K_3)在电极上的氧化还原性质,对维生素C和肼的氧化有很好的催化作用,其氧化峰电位分别降低220mV和562mV.The electrochemically polymerized o-phen film electrode is firstly reported in this paper. The CMEs prep by galvanostatic and potentiostatic methods and cyclic voltammetry, show good stability in acid, neutral and weak basic media. The electrocatalytic activity of CMEs towards K_3Fe(CN)_6、V_(k3)、V_c and hydrazine was studied. The peak potentials for oxidation of V_c and hydrazine shifted negatively by 220mV and 530mV,respectively.
