| Abstract: | By taking brine solution as the pore-forming agent, the rheological property of cast membrane solution, which consists of polysulfone and DMA/brine solution, is studied in this paper. The ultrafiltration property of the hollow fiber membrane there of prepared is tested and analysed also.In addition, a comparison of the membrane with those prepared by using an organic compound such as PVP or PEG as the pore-forming agent is made. The results show that the brine is an excellent pore-forming agent. |
