| 摘 要： | 选择掺杂过渡金属离子Fe^3 的纳米TiO2为催化剂，研究了US(超声波)／UV(紫外光)协同催化氧化水中对氯苯酚(4-CP)的降解效果，考察了对氯苯酚的起始浓度、超声波声强、溶液初始pH、饱和气体种类、反应温度和催化剂投加量对氯苯酚降解速率的影响．研究结果表明：US／UV协同催化氧化处理比单独超声波处理和光化学处理，4-CP降解速率提高了1．5～1．7倍，证实了声光联合技术具有明显的协同效应．

| Abstract: | Chlorophenol (4-CP) solution was treated by US(Ultrasound)/UV(Ultraviolet) synergetic catalysis technology and the major influencing factors such as the sound intensity, initial pH value of solution, initial 4-CP concentration, the amount of catalyst and medium temperature were examined in this paper. The results showed that that US/UV synergetic technology was superior to each of ultrasound irradiation and photochemistry alone. Within half an hour, the sum of 4-CP removal rates by as using ultrasound irradiation and photochemistry respectively to degrade 4-CP was obviously less than the removal rate by using US/UV synergetic technology. The significant synergetic effect of US/UV was identified. |
