Abstract: |
|
Sulfonated polyethersulfone(SPES)/polyethersulfone(PES) blend UF membrane with small pore size was prepared by the nonsolvent induced phase separation(NIPS) method, and the properties were also tested. The effects of solvents, concentration of polymers and the ratio of SPES to PES on membrane performance were considered. The result showed that the solvent had a huge impact on the membrane performance. The membrane made by dimethylacetamide (DMAc) had a better performance on flux and rejection. With an increasing of the concentration of polymers the flux of water decreased while the rejection of PEG-10000 increased first and then tended to be stable. The molecular-weight cut-off (MWCO) was under 6000Da, and the membrane was negatively charged blend UF membrane with small pore size by measuring the rejections of different solutions. On the basis of Matlab calculation, the pore size and MWCO of blend UF membrane were 1.98nm and 3060Da, respectively. |
