【摘要】 采用循环伏安法电化学聚合制备了聚苯胺/聚砜复合膜电极,研究了复合膜电极对对苯二酚和邻苯二酚的单组分及其混合体系的电催化氧化.结果表明聚苯胺复合膜电极具有很好的电催化作用,在混合体系中对苯二酚的一对氧化还原峰和邻苯二酚的两对氧化还原峰能够清楚地区分;并且在一定的浓度范围内单组分的浓度与峰电流呈良好的线性关系,说明该电极对苯二酚的测定在定性、定量中具有潜在的应用价值.更多还原

【Abstract】 Polyaniline(PAN)/polysulfone(PSF) composite film electrodes are successfully prepared by electropolymerization using cyclic votammetry technique.Their electrochemical behaviors for single solute and mixed systems of hydroquinone(H2Q) and pyrocatechol(PC) are investigated.A pair of redox peak of H2Q and two pairs of redox peaks of PC on the composite film electrodes can be obviously distinguished in their mixed systems,which show the composite film electrodes have excellent electrocatalytic activity for two dipheonls(hydroquinone and pyrocatechol).The linear relationship between the peak current and concentration is observed for single solute within the certain concentration range,implying that the composite film electrodes have a potential application in the qualitative or quantitative analysis of dipheonl.更多还原
