摘要

从废水中消除抗生素仍然是一项重大挑战。这项工作介绍了耐用的、高性能的吸附膜，通过在商业底物（称为TA- fe）上聚合单宁酸（TA）和Fe3+离子形成，以增强抗生素的去除。通过过滤过程，TA-Fe修饰膜（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对抗生素具有较高的去除能力，其透过率为3815 L m−2 h−1 bar−1，在1.3 min内的去除效率为96.7%，比传统方法快115倍。此外，即使在连续10次循环后，MCM也能保持99.4%的吸附能力。本研究为吸附膜技术的发展提供了新的途径，为抗生素在污染废水中的可持续吸附和分离提供了新的途径。

Metal–phenolic coating on membrane for ultrafast antibiotics adsorptive removal from water

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.
