采用传统电化学和新型光谱电化学池对4-氨基苯酚（4-AP）在金电极上进行了伏安和紫外-可见光谱电化学研究。作为基础电解质，使用乙腈和作为支持电解质的10（-2）M四丁基六氟磷酸铵和乙酸盐缓冲液（pH 4.6）溶液。4-AP在金电极上的电化学氧化电位在水溶液中>+0.1V，在乙腈溶液中>+0.5V。氧化产物的形成已被其特征在于在一个新的光学薄层光谱电化学池原位紫外-可见光谱。(C)2003爱思唯尔科技有限公司版权所有。
Voltammetric and UV-Vis spectroelectrochemical studies on 4-aminophenol (4-AP) at gold electrodes have been carried out in conventional electrochemical and in novel spectroelectrochemical cells. As base electrolytes acetonitrile with 10(-2) M tetrabutylammonium hexafluorophosphate as supporting electrolyte and acetate buffer (pH 4.6) solutions have been used. 4-AP was electrochemically oxidized at gold electrodes at potentials > +0.1 V in aqueous solutions and at potentials > +0.5 V in acetonitrile solutions. The formation of an oxidation product has been characterized in situ by UV-Vis spectroscopy in a novel optical thin-layer spectroelectrochemical cell. (C) 2003 Elsevier Science Ltd.
