| 摘 要： | 以对二氯苯作为目标模型物,考察了多种光敏剂对模型物的降解情况,优化筛选出光敏剂碱性品红、溴甲酚紫、荧光桃红、甲基橙.通过光敏化剂和二氧化钛协同非均相体系除去水中的对二氯苯,筛选出光敏剂荧光桃红协同效果最佳.曝气对比实验说明了补充溶解氧对敏化氧化是必要的.

| Abstract: | The photosensitizer-assisted photocatalytic oxidation of organic chlorine compounds had been investigated. Different photosensitizes were applied to degrade p-dichlorobenze in wastewater with granular TiO2 as photocatalyst. The photocatalytic efficiency of p-dichlorobenze degradation increased obviously under the existence of photosensitizer. The efficiency of p-dichlorobenze degradation was up to 94 % in 100 mins. Fluorescein red, fuchsin, bromcresol purple and helianthin B showed different photosensitizer-assisted effects. Fluorescein red was the best photosensitizer for the p-dichlorobenze degradation |
