【摘要】 本文利用旋转圆盘电极研究聚苯胺对抗坏血酸的电催化过程动力学.研究结果表明,在酸性溶液中聚苯胺膜电极对抗坏血酸的氧化反应有电催化作用,与在光玻碳电极上相比,其峰电位负移、峰电流增高;在低转速时是扩散控制,达一定转速后催化反应为控制步骤.更多还原

【Abstract】 The electrocatalytic kinetics of ascorbic acid by rotating disc electrodes with polyaniline film is studied. The result showed that ascorbic acid in aqueous solution could be electrocatalytical oxidized by polyaniline film electrodes. Shift for the oxidation potential of ascorbic acid and increasing for peak current of ascorbic acid are compared with bare glassy carbon electrode. It is diffusion control at low rotating rate; catalysis reaction is control step when rotating rate reached some degree.更多还原
