| 摘 要： | 以新生态MnO2作为催化剂对模拟苯酚废水进行了臭氧化处理,考察了不同条件对苯酚催化臭氧化过程的影响.结果表明,新生态MnO2对体系臭氧化过程中苯酚的降解和COD的去除有显著的促进作用,含催化剂时反应动力学受体系pH的影响程度明显减小.新生态MnO2对苯酚臭氧化反应的催化性能优于凹凸棒土.

| Abstract: | Fresh MnO2 synthesized as catalyst for ozonation of phenol in aqueous solutions,and the different conditions of catalytic ozonation have been investigated. The results show that fresh MnO2 has a remarkable effect on the degradation of phenol and the removal of COD in phenol ozonation,and reaction kinetics is dependent on the pH value of system a little when catalyst exists. The catalytic capability of fresh MnO2 is better than attapulgite for ozonation of phenol. |
