【摘要】 研究了在碱性磷酸盐缓冲溶液体系中,丹皮酚在固体电极上的电化学吸附氧化行为。与苯酚的电化学性质比较表明,碱性溶液中丹皮酚在电极表面上发生类似的不可逆的氧化。氧化产物发生随后化学反应,在电极表面生成致密的不导电聚合物膜。利用超微电极技术研究了丹皮酚电化学氧化的动力学过程,并用时间分辨快速扫描现场红外光谱电化学证明了电极表面的聚合物膜是芳醚类聚合物。更多还原

【Abstract】 The electrochemical behaviours of paeonol on different solid electrodes were studied by cyclic voltammetry in alkaline phosphat buffer solution.Comparative studies were carried out by using phenol under similar experimental conditions.The electrochemical oxidation of paeonol is irreversible,which produces a compact insulated polymeric film on the electrode surface,and the electrochemical oxidation dynamic process was studied on an ultramicroelectrode.The insulated polymeric film was proved to be polymer arylether by time-resolved rapid scan infrared spectroscopy更多还原
