摘要: Abstract A new kind of Fe3+/polyvinylidene fluoride membrane (PVDF)-poly methyl methacrylate (PMMA) asymmetric catalytic was prepared by the blending method. The hydrophilicity and antifouling properties Fe3+/PVDF increased significantly after blended with PMMA. influence some factors such as polymer ratio, concentration, additives, temperature coagulation bath on pure water flux, BSA retention were discussed. activity Fe3+/PVDF-PMMA evaluated degradation refractory dye Orange IV in presence H2O2. results showed that addition appropriate PMMA preparation has greatly decreased contact angle membrane. had better anti-fouling than membrane’s rate flux increase When mass ratio (PVDF)/(PMMA) was...
