Improving the properties of polymeric membranes for water filtration have inspired a lot of interest due to the undesirable long-term impacts. Some of the most recent achievements in this sector are the development of mixed matrix membranes (MMMs) and thin-film nanocomposites (TFNs). Here we describe the development of a novel cellulose triacetate nanofiber membrane made of α-Fe2O3/polyacrylonitrile (PAN)/CaCO3/cellulose triacetate (CTA). This multi-functional membrane is capable of adsorption and removal of heavy metal ions as well as organic pollutants, photocatalytic degradation of organic pollutants and remineralisation of water. Further, the membrane showed very good stability in the pH regime of 3–9 (environmental interest) and in different solvents. Moreover, the membrane could sustainably remineralize water with calcium (95 mg/L) up to 7 days. The adsorption abilities of the α-Fe2O3/PAN/CaCO3/CTA (FPCC) nanofiber membrane for lead and copper were 91 % and 77 % percent for 100 mg/L initial concentration of lead and copper, according to the results. Methylene blue (MB) and methyl orange, (MO) two organic contaminants that pollute water, are removed effectively at the rate of 96 % and 95 %, respectively. The development of such a multi-functional membrane opens up a new opportunity for solving drinking water concerns in the context of environmental remediation.

由于不利的长期影响，改善用于水过滤的聚合物膜的性能引起了很多兴趣。该领域的一些最新成就是混合基质膜 (MMM) 和薄膜纳米复合材料 (TFN) 的开发。在这里，我们描述了由 α-Fe2O3/聚丙烯腈 (PAN)/CaCO3/三乙酸纤维素 (CTA) 制成的新型三乙酸纤维素纳米纤维膜的开发。这种多功能膜能够吸附和去除重金属离子以及有机污染物，光催化降解有机污染物和水的再矿化。此外，膜在 3-9 的 pH 值范围（环境利益）和不同溶剂中表现出非常好的稳定性。而且，该膜可以用钙（95 毫克/升）可持续地再矿化水长达 7 天。结果表明，α-Fe2O3/PAN/CaCO3/CTA (FPCC) 纳米纤维膜对铅和铜的吸附能力在 100 mg/L 的铅和铜初始浓度下分别为 91% 和 77%。亚甲蓝 (MB) 和甲基橙 (MO) 是两种污染水的有机污染物，其有效去除率分别为 96% 和 95%。这种多功能膜的开发为解决环境修复背景下的饮用水问题开辟了新的机遇。亚甲蓝 (MB) 和甲基橙 (MO) 是两种污染水的有机污染物，其有效去除率分别为 96% 和 95%。这种多功能膜的开发为解决环境修复背景下的饮用水问题开辟了新的机遇。亚甲蓝 (MB) 和甲基橙 (MO) 是两种污染水的有机污染物，其有效去除率分别为 96% 和 95%。这种多功能膜的开发为解决环境修复背景下的饮用水问题开辟了新的机遇。
