摘　　要：本文将回归正交设计应用于聚砜超滤膜的制备中，获得了聚砜浓度、添加剂浓度及纺丝液温度与聚砜超滤膜对ＴＮＴ的截留率、透水速率关系的回归方程，确定出三因素的最优组合，使得该膜对ＴＮＴ的截留率较大。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.
