| Abstract: | Regenerated cellulose ultrafiltration membranes were prepared by using cellulose pulp plate, cotton and cellulose acetate, respectively. Cellulose membranes were formed directly by casting of cellulose solution and then coagulation. When cellulose acetate was used, cellulose acetate membranes were formed and then hydrolyzed to cellulose membranes. The cellulose membranes were investigated in ultrafiltration experiments with soy, medical liquor and milk to assess their resistance to fouling. Regenerated cellulose ultrafiltration membranes show high antifouling characteristics compared to polysulfone membrane and polyacrylonitrile membrane. |
