| 摘 要： | 采用臭氧氧化法处理对氯苯酚溶液,研究了pH、温度、气体流量和对氯苯酚初始浓度等因素对处理效果的影响.反应体系pH越高,越有利于氧化反应.用自制的载有Fe,Co,Mn氧化物的活性炭纤维(ACF)催化剂进行催化臭氧氧化对氯苯酚的实验.结果表明,Fe/ACF显示了较好的催化性能和活性.通过在反应体系中加入一定量的羟基自由基猝灭剂,初步探讨了其催化机理,即催化剂和臭氧反应生成了氧化性极强的羟基自由基. |

| Abstract: | Removal of p-chlorophenol(PCP) by ozone oxidation in the presence of metal coated activated carbon fiber(M/ACF) was studied to determine the effects of M/ACF catalyst,pH,temperature,initial concentration,and ozone-oxygen feed rate.The PCP removal rate increased with increasing pH,temperature,and gaseous feed rate;the removal rate declined at a higher initial PCP concentration when the availability of ozone might have become the limiting factor.The presence of M/ACF significantly enhanced the PCP removal,Fe was the most effective metal catalyst,followed by Mn,Co.The enhancement was likely due to the highly reactive hydroxyl radicals produced by catalytic oxidation. |
| Keywords: | M/ACF Catalyzed ozonation Hydroxyl free radical P-chlorophenol Catalytic mechanism |
