| 摘 要： | 研究了TiO2 光催化与光敏化协同处理有机氯化物废水的实验.普通的光催化降解和光敏化对五氯酚钠的降解率只能分别达到64.5%和78.8%,而二者的协同可使得同样条件下的降解率达到94.6%.实验结果还表明,不同的光敏化剂的影响效果各异.紫外谱图表明五氯酚钠的苯环特征峰经过降解可以完全消失.

| Abstract: | The photosensitizer-assisted photocatalytic system was constituted granular TiO_2 as photocatalyst. The photocatalystic efficiency of Na-PCP degradation was observed to be 64.5 % and 78.8 % respectively for common photocatalysis and photosensitization,while that to be 94.6 % for the combination of both of them, i.e., the photosensitizer-assisted photocatalytic system. According to the experimental results, the effect of every photosensitizer was different. UV spectra of Na-PCP indicated that benzene ring structure was destracted completely. |
