Abstract：

Fe　(III)-modified　polytetrafluoroethylene　(PTFE)　fiber　complex　was　prepared　with　poly　acrylic　acid　grafted　PTFE　fiber　and　FeCl3　aqueous　solution　and　used　a　novel　heterogeneous　Fenton　catalyst　for　the　photo-assisted　degradation　of　Rhodamine　B　in　water.　The　results　indicated　that　Fe　(III)-grafted　PTFE)　fiber　complex　can　significantly　enhance　the　dye　degradation　at　a　wide　pH　media　under　light　irradiation.　Increasing　Fe　content　of　the　catalyst,　H2O2　concentration　and　visible　irradiation　intensity　leads　to　a　fast　degradation.　Moreover,　UV　light　irradiation　is　much　more　effective　than　visible　light　irradiation　for　promoting　dye　degradation.　©　(2013)　Trans　Tech　Publications,　Switzerland.
