TI  - 2,4-dichlorophenol degradation by an integrated process: photoelectrocatalytic 
      oxidation and E-Fenton oxidation.
PG  - 642-6
AB  - A new reactor system was designed for an integrated process involving 
      photoelectrocatalytic oxidation (PECO) and electro-Fenton (E-Fenton) oxidation. 
      Its efficiency was evaluated in terms of 2,4-dichlorophenol (2,4-DCP) degradation 
      in aqueous solution. In this process, a TiO2 electrode and an iron (Fe) electrode 
      were used as anodes in parallel, while graphite felt (GF) was used as a cathode. 
      When an electrical current is applied between the anodes and the cathode, the 
      iron anode can release Fe2+ and the GF cathode can generate H2O2 continuously in 
      the reaction solution. Under UV-A illumination, while a H2O2-assisted PECO 
      reaction occurs on the surface of the TiO2 photo anode, an E-Fenton reaction 
      takes place in the solution. The experimental results demonstrated that 2,4-DCP 
      degradation in aqueous solution was greatly enhanced because of the interaction 
      between the two types of reactions. Moreover, the effect of pH as an important 
      factor was investigated. It was found that the combined reaction becomes less pH 
      sensitive than the typical E-Fenton reaction and may be suitable for application 
      in a wide pH range.
