摘要:
采用循环伏安法在不同性质介质中研究了β-PbO2—SPE复合膜电极上苯酚的降解能力.结果表明,在非酸性介质中,苯酚可直接电化学降解,且在碱性介质中降解能力强于中性介质.降解机理分析推断:碱性介质中降解反应的电子转移系数为0.127,中性介质中为0.156.不同速率下的CV性能研究表明,苯酚在这两种介质中降解过程受扩散控制.
Abstract:
In this paper, the electrocatalytie degradation properties of phenol on β-PbO,-SPE compositemembrane electrode in different media were investigated with cyclic voltammetry ( CV) method. The CV experimental results show that, only in the alkali and intermediate media, the phenol can be directly destroyedand the degradation power in alkali media goes beyond to intermediate media. The electron transfer coefficientsare calculated which is 0. 127 in alkali media, and is 0. 156 in intermediate media. The CV curves in differentscanning rates show that the degradation reactions were controlled by diffuse processes.
