| 摘 要： | 研究了在微波/过氧化氢（MW/H2O2）系统下苯酚的降解效果，并且详细探讨了影响MW/H2O2系统催化氧化降解苯酚的各种因素。实验结果表明：在单独的微波辐照或者过氧化氢氧化下苯酚去除率很小，而在MW/H2O2组合氧化系统中有显著的提高，苯酚降解的拟一级动力学速率常数增强因子可达到5.98，表明存在明显的协同效应。另外，在实验中加入Fe2+能加速苯酚的降解。

| Abstract: | Phenol aqueous solution was treated by microwave(MW)/H2O2 combined technology and the affecting factors were studied.Experimental results showed that the removal efficiency of phenol was low when microwave irradiation process and H2O2 oxidation were used separately.MW/H2O2 combined technology was favorable for enhancing the removal efficiency of phenol,with the enhancement factor of the first-order kinetics constant being around 5.98.The synergetic effect of MW/H2O2 combined technology was obvious.The co-existence of Fe2 had significant influence upon MW/H2O2 combined technology,and Fe2 increased the reaction rate. |
