Eliminating antibiotics from wastewater remains a critical challenge. This work introduces durable, high-performance adsorptive membranes formed by polymerizing tannic acid (TA) and Fe³⁺ ions on commercial substrates, known as TA-Fe, to enhance antibiotic removal. Using a filtration process, the TA-Fe modified membrane (MCM) demonstrated excellent ciprofloxacin hydrochloride removal efficiency, permeance, and reusability. The MCM achieved high removal capability for antibiotics, with a permeance of 3815 L m⁻² h⁻¹ bar⁻¹ and 96.7% removal efficiency within 1.3 min—115 times faster than traditional methods. Furthermore, the MCM sustained an impressive adsorptive capacity of 99.4% even after 10 consecutive cycles. This work profoundly progresses the domain of adsorptive membrane technology, offering a promising avenue for the sustainable adsorption and separation of antibiotics from contaminated wastewater.

从废水中消除抗生素仍然是一项严峻的挑战。这项工作介绍了通过在商业基材上聚合单宁酸 （TA） 和 Fe³⁺ 离子形成的耐用、高性能吸附膜，称为 TA-Fe，以增强抗生素去除。使用过滤工艺，TA-Fe 改性膜 （MCM） 表现出优异的盐酸环丙沙星去除效率、渗透性和可重复使用性。MCM 对抗生素的去除能力很高，渗透率为 3815 L ^{m-2 h-1 bar-1}，在 1.3 分钟内去除效率为 96.7%，比传统方法快 115 倍。此外，即使在连续 10 次循环后，MCM 仍保持了令人印象深刻的 99.4% 吸附容量。这项工作深刻地推动了吸附膜技术领域的发展，为从受污染的废水中可持续吸附和分离抗生素提供了一条有前途的途径。
