摘要
用紫外辐照的方法改性聚砜超滤膜，紫外辐照后膜性能的变化与辐照时间、改性剂种类、改性剂浓度等有关．聚砜超滤膜经紫外辐照改性后，通量增加、膜的亲水性增强．并讨论了紫外辐照改性超滤膜的机理．
In this paper, hydrophobic polysulfone membranes were modified by UV irradiation. After modifying membranes by irradiation, the properties of the membranes were effected by the time of irradiation, the kinds and concentration of modification agents used UV irradiation increased flux and the hydrophilicity of the membranes. The mechanism of modification membrane by UV irradiation were discussed.
