| 摘 要： | 为提高高级氧化技术对内分泌干扰物的降解和矿化性能,首次研究了(TiO2/Ti-Fe)-石墨毡双阳极光电协同催化氧化体系,并考察了其对2,4-二氯苯酚的光催化氧化降解性能.研究了电流在TiO2/Ti-Fe两阳极上的分配,外加电压,pH等主要因素对2,4-二氯酚降解效率的影响及反应过程中H2O2的生成及积累情况.实验结果表明,本体系不仅具有较高的H2O2生成效率和较强的光催化氧化降解性能,而且该体系可以在较宽的pH范围内工作.在较低的电流密度下反应60 min,2,4-二氯酚的降解率可达95%以上,而矿化率高达80%.

| Abstract: | To increase the degradation ability of some advanced oxidation processes(AOPs),the double-anode photoelectrocatalytic oxidation(PECO) process was studied and the degradation of 2,4-dichlorophenol(2,4-DCP) was investigated.The effects of current distribution,adscititious voltage and pH on the degradation efficiency were studied.Furthermore,the generation and accumulation of H2O2 were researched during the degradation of 2,4-DCP.Results show that this process has powerful generation efficiency of H2O2 and pow... |
