Abstract

Water scarcity has become one of the most significant problems globally. Membrane technology has gained considerable attention in water treatment technologies. Polymeric nanocomposite membranes are based on several properties, with enhanced water flux, high hydrophilicity and anti-biofouling behavior, improving the membrane performance, flexibility, cost-effectiveness and excellent separation properties. In this study, aminated graphene oxide (NH-GO)-based PVDF membranes were fabricated using a phase-inversion method for textile dye removal. These fabricated membranes showed the highest water flux at about 170.2 (J/L.h.m) and 98.2% BSA rejection. Moreover, these membranes removed about 96.6% and 88.5% of methylene blue and methyl orange, respectively. Aminated graphene oxide-based polyvinylidene fluoride (PVDF) membranes emerge as a good membrane material that enhances the membrane performance.

摘要

水资源短缺已成为全球最严峻的问题之一。膜技术在水处理技术中备受关注。聚合物纳米复合膜基于多种特性，具有增强的水通量、高亲水性和抗生物污染性能，可改善膜的性能、柔韧性、成本效益及优异的分离性能。在本研究中，采用相转化法制备了基于胺化氧化石墨烯（NH-GO）的聚偏氟乙烯（PVDF）膜用于去除纺织染料。这些制备的膜在约170.2（J/L.h.m）时显示出最高水通量以及98.2%的牛血清白蛋白截留率。此外，这些膜分别去除了约96.6%的亚甲基蓝和88.5%的甲基橙。基于胺化氧化石墨烯的聚偏氟乙烯（PVDF）膜成为一种能提升膜性能的优质膜材料。
