| Abstract: | In this paper the regression orthogonal design was applied to the preparation of polysulfone(PS) ultrafiltration membranes, and the regression equations of cutoff ratio to TNT molecule and water flow rate with PS concentration, additive concentration and spinning temperature were obtained. The optimum combination of three factors was determined, and the membranes have higher cut off ratio to TNT and higher water flow rate. |
