摘要/Abstract

摘要： 通过表面化学法将阴离子聚丙烯酰胺接枝到醋酸纤维素微滤膜上,得到聚电解质改性膜。实验研究了阴离子聚丙烯酰胺质量分数、交联剂质量分数、交联反应温度和反应时间对接枝率、改性膜的水通量和截留率的影响。结果表明,聚电解质质量分数越高、交联剂质量分数越大、反应时间越长、反应温度越高,膜的水通量越低而截留率越高。

关键词: 表面化学法, 阴离子聚丙烯酰胺, 醋酸纤维素微滤膜

Abstract: The cellulose acetate (CA) microporous membranes weremodified by chemical surface-grafted method with anionic polyacrylamide.The effects of concentration of anionic polyacrylamide and cross-linking agent,reaction time and temperature on grafting yield and the flux and rejection of graftedmembrane were investigated.The results show that the flux of modified membranesdecreased while the rejection increased with increasing concentration of anionicpolyacrylamide and cross-linking agent,extending reaction time,raising reaction temperature.

Key words: chemical surface-grafted method, anionic polyacrylamide, microporous cellulose acetate membrane
