| titleOfInvention | A kind of nanoparticle modified PVDF ultrafiltration membrane composite material and its preparation method and application |
| abstract | The invention discloses a nanoparticle-modified PVDF ultrafiltration membrane composite material and a preparation method and application thereof. The preparation method includes the following steps: firstly, CNTs/PVDF ultrafiltration membrane is prepared by using carboxylated multi-walled carbon nanotubes, PVDF and PVP. filter membrane; then soak it in a mixed solution consisting of sodium chloride, anhydrous ethanol, deionized water, an acidic ferrous sulfate solution, and potassium borohydride solution in turn; pass MWCNTs-COOH, nZVI to PVDF ultrafiltration membrane Modification treatment is carried out to develop a nano-particle modified PVDF ultrafiltration membrane with good treatment effect on dye wastewater. After modification, the water flux and treatment rate of the ultrafiltration membrane are obviously improved. The material of the invention is convenient to manufacture and easy to operate. The modified membrane has the characteristics of high permeability and excellent hydrophilicity. |
