Poly

Poly(tetrafluoroethylene-co-hexafluoropropylene) (FEP)/ferric oxide (Fe.sub.2O.sub.3) hybrid flat-sheet membranes (HFM) (FEP/Fe.sub.2O.sub.3-HFM) with heterogeneous Fenton-like oxidation were fabricated by a facile hot pressing method for dye effluent treatment. The morphology and properties of the resultant membrane were found to be influenced by the addition of Fe.sub.2O.sub.3. With the increasing Fe.sub.2O.sub.3 content, the porosity, water flux and contact angle of the resultant FEP/Fe.sub.2O.sub.3-HFM will raise up but deteriorate mechanical performance. The maximum methylene blue (MB) removal efficiency (99.69%) can be achieved using 10 wt% Fe.sub.2O.sub.3 addition in membrane composition at following conditions: 40 mg L.sup.-1 MB concentration at pH 3, the dosage of 1.5 g g.sup.-1 (hydrogen peroxide, H.sub.2O.sub.2 to FEP/Fe.sub.2O.sub.3-HFM) in cross-flow filtration. In addition, FEP/Fe.sub.2O.sub.3-HFM shows commendable reusability enduring vigorous catalysis due to the inherit stability from fluorinated polymer. Due to high-efficient separation and good removal performance to high concentration of dye (e.g. 250 mg L.sup.-1 MB), our FEP/Fe.sub.2O.sub.3-HFMs show great promise in aqueous pollutant treatment by heterogeneous Fenton-like reaction.
