摘　　要：本文以聚砜和磺化聚砜为原料,制备了低截留分子量的共混超滤膜,此种膜具有适中透水量,对分子量3000的PEG截留率在90％以上。对膜的制备参数,如聚合物浓度、不同溶剂、不同添加剂和凝胶介质对膜性能的影响进行了较详细的研究。The blend ultrafiltration membrane of the polysulfone and sulfonated polysulfone has been obtained. This membrane has moderate water flux, more than 90% retention for PEG 3000.The effects of polymer concentration, different solvents, additives, and coagulating media on membrane performance have been studied in detail.
