| Abstract: | Cellulose membranes were prepared successfully from N -Methylmorpholine- N -Oxide(NMMO) solution. During the process,cellulose solution from different pulp with different cellulose concentration was immersed into water bath with various NMMO concentration under different bath temperature.Depending on the precipitation conditions,the new membrenes have asymmetric or asymmetric cross-sectional mophology and pore structure,which is observed from SEM photographs.The influence of different conditions on the flux and BSA(Bovine Serum Albumin) rejection of membranes was discussed either. |
