摘要
本文以聚砜酰胺(PSA)为膜材,N—甲基吡咯烷酮(NMP)为溶剂,研究了凝胶介质的种类、浓度、温度对超滤膜结构和性能的影响。并得到相应的通量和截留率的拟合方程。
PSA and NMP were employed as membrane material and a slovent respectively. The influnce of the type, concentration and temperature of the gel media on membrane structure and performance was investigated. The fitting equations of flux and rejection were obtained.
