【摘要】 通过改变铸膜液中添加剂PEG的含量,测试了当铸膜液中PES的质量分数为0.21,凝固浴(DM SO/H2O体系)中DMSO的质量分数为0.10时,所成膜的水通量和尿素、肌酐去除率。研究了PES/DMSO体系中小分子添加剂PEG作用的规律。更多还原

【Abstract】 The content of PEG with low molecular weight in the casting solution is changed when PES casting solution forms membranes. The content of PES in the casting solution is 21% and the content of DMSO in the coagulation bath(DMSO/H2O) is 10%. The pure water flux, elimination ratio of urea and creatinine of PES membranes formed are tested. The effecting rule of PEG with low molecular weight on the system of PES/DMSO is studied.更多还原
