Study on the preparation and characteristics of PVDF/CA blend ultrafiltration membrane |
| |
| Abstract: | The PVDF/CA blend ultrafiltration membranes were made by phase reverse method,which were characterized by water flux,protein retention,chemical stability and antifouling. The effects of the preparation parameters such as addictive species,coagulation bath and the mass ratio of PVDF to CA on the membrance performance were investigated.And the compatibility between PVDF and CA was early discussed. |
