| 摘 要： | 采用截留相对分子质量为6000的中空纤维超滤膜,对不同相对分子质量的聚乙二醇(PEG)溶液进行了截留实验。讨论了超滤对不同相对分子质量聚乙二醇的去除效果,研究了过滤时间、操作压力及料液质量浓度对聚乙二醇去除效果的影响。最佳分离条件为:操作压力0.05 MP,PEG相对分子质量20000,料液质量浓度100 mg/L,过滤时间5 min。

| Abstract: | In this paper,using MWCO 6000 UF membranes,the retention experiments of PEG with different molecular weights were carried out.The removal effect of ultrafiltration membrane on different molecular weights PEG was discussed;the influences of operation conditions on the removal effect of PEG were investigated,such as filter time,operation pressure and feed concentration.The optimal conditions are obtained： operation pressure is 0.05 MP,PEG molecular weight is 20000,PEG concentration is 100 mg/L and filter time is 5 minutes. |
