以聚硫酸(酰胺)酯为原料、
N
N
-二甲基甲酰胺(DMF)为溶剂,聚乙烯吡咯烷酮(PVP)为添加剂,通过相转化法制备了具有高水渗透性和优异抗污染性能的新型聚硫酸(酰胺)酯超滤膜。实验结果表明,随着聚硫酸(酰胺)酯含量的增加,超滤膜的亲水性和抗污染性能显著提高。当聚硫酸(酰胺)酯质量分数为18 wt%时,所制备的超滤膜对腐植酸溶液的截留率达到88.65%,同时保持85.25%的通量恢复率,这为高性能超滤膜的制备提供了重要参考。
Novel poly(sulfonate(amide) ester) ultrafiltration membranes were prepared using polysulfonamide as the raw material
N
N
-dimethylformamide (DMF) as the solvent
and polyvinylpyrrolidone (PVP) as the additive
via
phase inversion. The results showed that with an increase in the Poly(sulfonate(amide) ester) content
the hydrophilicity and antifouling properties of the ultrafiltration membranes increased. When the poly(sulfonate(amide) ester) content was 18 wt%
the rejection rate of the prepared ultrafiltration membrane for humic acid solution was 88.65%
and it could maintain a flux recovery rate of 85.25%. This has profound significance for the preparation of high-performance ultrafiltration membranes.
