Comparative Studies of Two Fenton-Like Catalysts: Fe₂O₃ and Fe₂O₃/Attapulgite

Abstract:

Fe₂O₃ and Fe₂O₃/attapulgite(ATP) catalyst was used for Fenton reaction to degrade an anion surfactant, sodium dodecyl benzene sulfonate(SDBS)，in an aqueous solution. Comparative studies indicated that Fe₂O₃/ATP-catalyzed Fenton system and Fe₂O₃-catalyzed Fenton system have the same catalysis capability. These two systems all have a widely pH range (2-10), and the catalysts can be reused and have no secondary pollutants. It also can be seen that Fe₂O₃/ATP-catalyzed Fenton-like reaction has much efficiency than Fe₂O₃-catalyzed Fenton reaction.
