| 摘 要： | 利用O3／UV、TiO2／UV和O3／TiO2／UV降解对氯苯酚表明，臭氧与TiO2／UV具有明显的协同作用，如在本实验条件下降解5min后，上述3者对对氯苯酚的去除率分别为55％、10％和77%。O3／TiO2／UV协同作用的本质是由于臭氧能带走二氧化钛光致电子空穴对中的电子，从而产生了更多的羟基自由基，加速了有机物的降解。

| Abstract: | P\|chlorophenol in water was degraded by O 3/UV?TiO 2/UV and O 3/TiO 2/UV. The results showed that ozone combined with TiO 2/UV is the most signficant. After 5 min under the same experimental condition, the removal rates of P\|chlorophenol by O 3/UV?TiO 2/UV and O 3/TiO 2/UV were 55%,10% and 77%, respectively. The nature of degradation of P\|chlorophenol by ozone combined with TiO 2/UV is the ozone can capture the electrons of TiO 2 (e\+- h\++) when TiO 2 adsorb the UV light, then produces the more hydroxyl radical to faster the degradation of organic matter. |
