木质素添加对基膜及纳滤膜结构和性能的影响
Effect of lignin addition on the structure and performance of substrate and nanofiltration membrane
摘要
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 Na2 SO4 solution by blending lignin NF membrane in-creased 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.关键词
