| 摘 要： | 研究了US/Fenton协同作用对水中苯酚的降解效果,探讨了Fenton试剂浓度、H2O2/Fe2 配比、溶液pH值等对苯酚降解效果的影响.结果表明:Fenton试剂投加量的增加对降解反应先促进后抑制;当H2O2/Fe2 配比为40∶1,H2O2投加量为40mmol/L,溶液pH值3.0～7.0时,US/Fenton对苯酚的降解速率最快,反应30min后的降解效率远大于单独US、Fenton试剂氧化处理下的降解效率总和,其表现一级动力学速率常数增强因子可达到2.45,表明US/Fenton联用存在明显的协同效应.

| Abstract: | Degradation of phenol in aqueous solution by US/Fenton reagent technology and the major affecting factors were examined in batch experiments.Results indicated that the degradation rate was increased first and then declined with the increasing of the dose of Fenton reagent.With optimum conditions,H_2O_2/Fe~(2+)ration of 40:1,H_2O_2 dose of 40 mmol/L and pH range of 3.0 to 7.0,the addition of Fenton reagent could accelerate the degradation rate.Within 30 min,the removal rate by using US/Fenton reagent technology was obviously over the sum removal rate of using US and Fenton reagent oxidation respectively,with an enhancement factor of the first order kinetic constant being around 2.45.The synergetic effect of ultrasound/Fenton reagent technology was obviously. |
