| titleOfInvention | Based on metal-doped nTiO2Visible light catalytic hollow fiber ultrafiltration membrane and preparation method |
| abstract | The invention discloses one kind to be based on metal-doped nTiO 2 Visible light catalytic hollow fiber ultrafiltration membrane and preparation method, belong to technical field of membrane separation.By the polysulfones of 10.0%~25.0% (w/w) or polyether sulfone, the pore-foaming agent of 8.0%~17.0% (w/w), the surfactant of 0.1%~2.0% (w/w), 0.1%~5.0% (w/w) metal-doped nTiO 2 It is added in dissolving tank in a certain order with the solvent of 51.0%~81.8% (w/w), standing and defoaming 8~36 hours, casting solution is made to being completely dissolved within stirring and dissolving 5~16 hours at a temperature of 35~95 DEG C；Visible light catalytic hollow fiber ultrafiltration membrane is prepared using traditional dry-wet spinning technique.Pure water flux >=300L/m of ultrafiltration membrane prepared by the present invention 2 Hr0.1MPa, bovine serum albumin rejection >=90.00% are run 1 hour under degradation removal rate >=60%(simulated visible light of fulvic acid), there is good antifouling property and visible light catalytic performance.Product of the present invention is especially suitable for micro-polluted source water advanced treating, seawater desalinization pretreatment and biochemical industry, the advanced treating of field of medicaments waste water and reuse etc.. |
