推导了苯酚液相臭氧氧化和复合氧化(O_3/H_2O_2)反应动力学模型,研究了苯酚液相臭氧氧化和复合氧化过程的降解,得出了苯酚液相臭氧氧化和复会氧化在温度288～313K和pH3.2～9.8条件下的反应动力学,探讨了反应机理,认为:在酸性(pH3.2)及弱酸性(pH6.2～6.5)时,苯酚的臭氧化和复合氧化降解反应均为O_3分子的直接氧化过程;在碱性(pH9.8)条件下,苯酚复合氧化降解机理以自由基反应为主。
The reaction kinetics model of ozone oxidation and compound oxidation (O_3 / H_2O_2) of phenol was deduced. The degradation of phenol in the liquid phase of ozone oxidation and composite oxidation was studied. The results showed that the oxidation and reoxidation of phenol in liquid phase at the temperature of 288 ~ 313K and pH3.2 ~ 9.8, the reaction mechanism was discussed. It was concluded that the ozonation and combined oxidative degradation of phenol both in acid (pH3.2) and weak acid (pH6.2 ~ 6.5) For the direct oxidation of O_3 molecules; Under the alkaline (pH9.8) conditions, the oxidation of phenol degradation degradation mechanism of free radical reaction based.
