| Abstract: | Flat ultrafiltration membrane of Polyethersulfone(PES) was successfully prepared by means of phase inversion method,with PES as raw material,polyethylene glycol 600(PEG600) as additive,N,N-dimethylformamide(DMF) as solvent and pure water as coagulation bath.The influence of PES concentration,PEG content and bath temperature on membrane performance and structure was discussed in detail.Based on the experiment results,the optimum conditions for preparing ultrafiltration membrane with high water flux and high rejection rate were determined. |
| Keywords: | polyethersulfone polyethylene glycol 600 membrane performance and structure |
