| 摘 要： | 研究了光催化光敏化氧化含酚含氯废水的降解情况。以五氯酚钠和对苯二酚混合溶液为目标物，用二氧化钛作光催化剂，对三种光敏化荆亚甲基蓝、玫瑰红B、曙红Y对其协同效果进行了考察。实验结果表明，光解反应、光催化反应、光敏化反应以及光催化光敏化共同反应中，后者的光解率是最好的。在相同的条件下，反应100min左右，混合废水的降解率分别约为5％、50％、70％、92％。紫外图谱表明，难降解的有机大环的特征峰在光催化光敏化氧化过程中逐渐消失。

| Abstract: | The photosensitizer-assisted photocatalytic system was constituted granular TiO_2 as photocatalyst. The photocatalystic efficiency of contaminants degradation was observed to be 50 % and 70 % respectively for common photocatalysis and photosensitization,while that to be 92% 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 mixture waste water indicated that benzene ring structure was destracted completely. |
