Preparation method of polytetrafluoroethylene film for catalytic decolorization of dye and application method of polytetrafluoroethylene film |
| abstract |
The invention relates to a preparation method of a polytetrafluoroethylene film used for catalytic decolorization of dyes and an application method of the polytetrafluoroethylene film, belonging to the technical field of water treatment. In the preparation method of the polytetrafluoroethylene film used for the catalytic decolorization of dyes of the present invention, the 2-hydroxyethyl methacrylate (HEMA) solution is grafted to the polytetrafluoroethylene microporous film by the γ-ray irradiation method. The surface is then subjected to activation treatment and chelation treatment, and the treated film is coupled with metal ions to obtain the polytetrafluoroethylene film for catalytic decolorization of dyes. The preparation method of the polytetrafluoroethylene film for dye catalytic decolorization of the present invention is simple and easy to implement, and the cost is low, and the prepared film not only has excellent corrosion resistance, mechanical strength and low resistance, but also has excellent catalytic degradation. The performance of the dye is improved, and the decolorization efficiency of the dye is improved; the invention also provides a simple application method of the polytetrafluoroethylene film. |
