Phenol degradation by MnO2 assisted Fenton reagent oxidation technology
MnO2催化Fenton试剂降解苯酚废水

The kinetics character and removal effect on high-concentration phenol degradation by MnO2 assisted Fenton reagent oxidation technology were researched. The results show that the removal efficiency of phenol and COD are significantly enhanced by using MnO2. Phenol degradation follows First-order reaction under individual Fenton reagent process and MnO2 assisted Fenton reagent oxidation technology. The constant of phenol degradation velocity is enhanced and activation energy is reduced, showing that Fenton reaction could be easily occurred by using MnO2. From the UV-Vis absorption spectra and FTIR spectra of wastewater, carboxylic acids and olefins organic intermediates may be produced.
