Characterization and Catalytic Activity of Fenton-Like Catalyst: Fe₂O₃/Attapulgite

Abstract:

Fe₂O₃/attapulgite(ATP) catalyst was successfully prepared for Fenton reaction to degrade an anion surfactant, sodium dodecyl benzene sulfonate(SDBS)，in an aqueous solution. BET, SEM, FT-IR were performed to characterize Fe₂O₃/ ATP catalyst. Comparative studies indicated that the SDBS degradation ratios were much higher in presence of Fe₂O₃/ATP and H₂O₂ than those in presence of Fe₂O₃/ATP or H₂O₂ only, which suggested that the Fe₂O₃/ATP-catalyzed Fenton-like reaction governed the SDBS removal process. It also can be seen that Fe₂O₃/ATP-catalyzed Fenton-like reaction almost has the same efficiency as homogeneous Fenton reaction, while the former can be reused and has no secondary pollutants.
