摘要:
本文制备了以共混聚砜(PSf)/磺化聚砜(SPSf)材料为基膜,聚酰胺为活性层的复合正渗透膜,并以D-葡萄糖胺(D-GlcN)为改性剂对初生的聚酰胺层进行接枝改性以提升复合膜的渗透和耐污染性能。对D-GlcN改性膜进行了结构表征和性能测试,ATR-FTIR和XPS结果表明D-GlcN已成功接枝到膜表面。改性后复合膜的水通量增加,当D-GlcN质量浓度为3%时达到最大,活性层朝向汲取液侧模式(AL-DS模式)下为31.1 L/(m2·h),相对于未改性膜提升22%,且改性后复合膜的反向盐通量几乎未发生改变。使用两种不同电荷性质的模拟污染物进行了耐污染测试,结果表明,改性膜的耐污染能力有所提升。
 A thin-film composite forward osmosis (TFC FO) membrane was fabricated in this work by using PSf/SPSf membrane as the supporting structure and polyamide as the active layer. TFC FO was further modified by grafting glucosamine (D-GlcN) on the nascent polyamide active layer to improve its permeation flux and pollution resistance. The results of Fourier transform infrared spectroscopy (ATR-FTIR) and X-ray photoelectron spectroscopy (XPS) indicate D-GlcN has been grafted onto polyamide layer successfully. The permeation flux of each membrane was tested, and the maximum flux of the modified membrane was increased by 22% compared with the original TFC membrane, reaching 31.1 L/(m2·h) in AL-DS mode, while the reverse salt flux was almost unchanged. The fouling resistance of the modified membrane was studied with sodium alginate solution and dodecyl trimethyl ammonium bromide. The results showed that the fouling resistance of modified film is better than pristine membrane.
