摘要
以苯胺及其衍生物为研究对象 ,探讨了不同有机化合物结构对超声光催化降解的影响 ,进一步开拓了基于超声波与TiO2 光催化联合催化降解有机废水的新型深度氧化处理新技术 超声光催化技术 .实验结果表明 ,尽管超声光催化反应对苯胺及其衍生物的降解协同效应并不是很显著 ,但是超声光催化反应对苯胺及其衍生物却具有较好的降解率 。
The effects of compounds with different structures on their sonophotocatalytic degradation were investigated in detail, using aniline and its derivatives as model pollutant, and a new Advanced Oxidation Processes (AOPs), sonophotocatalysis which combined the photocatalysis with ultrasonic technology, was pioneered for degrading organic pollutants. The experimental result showed that the synergetic effect was not as significant as expected, but the sonophotocatalytic technology have good COD removal efficiencies, furthermore, the compounds with different structures also played an important role in the sonophotocatalytic reaction.
