摘要
生物基膜因其廉价和可持续的优点而受到越来越多的关注。本研究通过引发胶原纤维(CFs)与单宁酸(TA)之间的交联反应，采用界面聚合(IP)工艺制备了一种新型薄膜复合纳滤(TFC)膜。随着TA浓度的增加，TFC膜的交联度提高，活性层变厚，膜顶表面变粗糙。在0.60 mg TA的优化条件下，TFC-3膜的透水性达到23.49 L m−2 h−1 bar−1，对刚果红、活性蓝19、考马斯蓝G-250和甲基蓝的拒绝率高达98.0%以上。此外，该膜保持了良好的盐保留率(Na2SO4为93.3%，MgSO4为83.4%，MgCl2为36.2%，NaCl为26.4%)，并具有良好的操作稳定性。这种表面制备方法为利用生物质进行分子精确分离提供了新的思路。图形抽象
Composite nanofiltration membrane with tannic acid coordinated collagen fibers for enhanced molecule separation
Biomass-based membranes have attracted increasing attentions due to their cheap and sustainable advantages. In this work, a novel thin-film composite (TFC) nanofiltration (NF) membrane was fabricated through a facial interfacial polymerization (IP) process by initiate the crosslinking reaction between collagen fibers (CFs) and tannic acid (TA). The increased TA concentrations endowed the TFC membrane with a higher crosslinking degree, a thicker active layer and a rougher top surface. At optimized condition with 0.60 mg TA decoration, the TFC-3 membrane exhibited a high water permeability of 23.49 L m−2 h−1 bar−1 with high rejections above 98.0% for congo red, reactive blue 19, coomassie blue G-250, and methyl blue. Furthermore, the membrane preserved remarkable salt retentions (93.3% for Na2SO4, 83.4% for MgSO4, 36.2% for MgCl2, and 26.4% for NaCl) and satisfying operation stability. This facial fabrication method offered a new insight to employ biomass for molecular precise separation.
