摘　　要：本文主要研究磺化聚矾超滤膜的截留分子量与影响膜性能的聚合物浓度、添加剂浓度、蒸发时间、凝胶介质和热处理温度等诸因素的关系。利用截留率曲线以及电荷强弱和密度的原理,定性地阐述膜截留分子量范围,并对其化学稳定性及其应用进行了初步探讨。This paper mainly studied the relationship of the retention characterization with the factors influencing SPS membrane performances, such as polymer concentration, additives concentration, evaporation time, gelation media and heattreatment temperature. The range of retention molecular weight may be qualitatively prescribed by retention property curve and principle of electric charge intensity and density. The chemical stability and the application of the SPS membrane were early investigated.
