[Removal of PAEs by combined activated carbon-Fenton process].
Removal of PAEs by combined process of activated carbon-Fenton was investigated. Factors associated with PAEs removal ratio following amount of activated carbon, dosages of oxidant, catalyst, initial concentration of PAEs, pH value and reaction time were studied. Results showed that high purification performance could be obtained by the synergetic effect of Fenton reagent and activated carbon. Average removal ratio of PAEs was 99.1% for the solution containing 12 mg x L(-1) DMP, DEP, DBP, DOP respectively by the activated carbon-Fenton process for 15 h.
