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.
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。
