摘要:
为了打破纳滤膜渗透性能与截留性能之间的权衡效应,通过在基膜中共混生物质材料木质素来调控界面聚合。在界面聚合过程中,基膜中的木质素吸附胺单体并抑制其扩散,从而使得聚酰胺选择层更薄、更致密。相较于传统的纳滤膜,在0.6 MPa下,基膜共混木质素纳滤膜过滤硫酸钠的渗透通量从84.6 L·m-2·h-1提高到139.2 L·m-2·h-1,截留率从93.4%提高到96.0%。这不仅能够为高性能纳滤膜的制备提供思路,同时为生物质利用提供新方向。
Abstract:
To break the trade-off between the permeability and rejection performance of nanofiltration(NF)membrane, the interfacial polymerization(IP)reaction is regulated by blinding biomass material lignin in the substrates. During the IP process, lignin in the substrate adsorbed amine monomers and inhibits their diffusion rate, resulting in a thinner and denser polyamide selective layer. Compared to traditional NF membranes, the permeability of Na2SO4 solution by blending lignin NF membrane increased from 84.6 L·m-2·h-1 to 139.2 L·m-2·h-1, and the rejection increased from 93.4% to 96.0%. This work not only provides ideas for the preparation of high-performance NF membranes, but also provides solutions for biomass utilization.
