摘要
用电化学及光谱电化学研究了硫酸溶液中苯胺在玻碳电极上的聚合降解过程 ,在 - 0 2～ 1 0V电位范围 ,循环伏安图显示了四对氧化还原峰 .通过比较聚苯胺 (PAn)膜在硫酸空白溶液和含对氨基苯酚 (PAP)的硫酸溶液中的循环伏安曲线及电化学聚合时溶液的紫外 可见吸收光谱 ,证明了PAn膜的降解产物PAP的存在 ,同时原位现场紫外 可见吸收光谱法初步研究了苯胺聚合降解的动力学过程 .
The degradation process of aniline on glassy carbon electrode during polymerization was investigated by electrochemistry and spectrum electrochemistry. Cyclic voltammograms showed four redox peaks within the potential limit of -0.2 to 1.0 V. The cyclic voltammetric curves of the PAn films in H2SO4, aqueous solution with/without containing PAP were compared, and the absorbance of the aniline electrolyte during polymerization was in situ measured by UV-Visible absorption spectrum. The results displayed the existence of PAP, which was the degradation product of the PAn films. The kinetic degradation process of aniline during polymerization was also in situ preliminarily investigated by UV-Visible absorption spectrum.
