Membrane separation has been widely used to address the global water crisis, but is limited by the permselectivity trade-off. Herein, an effective strategy was adopted to overcome this drawback by integrating membrane separation with peroxydisulfate (PDS) activation on a carbon nanotube (CNT) hollow fiber membrane. During the phenolic wastewater treatment, the CNT hollow fiber membrane not only performed as the separation barrier, but also as the catalyst to activate PDS to degrade the micro-size phenol timely. Compared to the sole filtration (33%), the advanced oxidation functions (AOFs)-based membrane has a higher phenol removal rate (97%) under the optimal conditions: neutral condition (pH = 6), 0.5 mM PDS, and hydraulic retention time (HRT) of 39.6 s. The separation mechanism was confirmed to be the non-radical reaction pathways (electro-transfer, and ¹O₂) through radical quenching, electron paramagnetic resonance (EPR), linear sweep voltammetry (LSV), and open circuit potential model. Such results suggested this work exhibited a high promising prospect for the remediation of organic pollution by a CNT hollow fiber membrane with AOFs.

膜分离已被广泛用于解决全球水危机，但受到渗透选择性权衡的限制。在此，通过将膜分离与过二硫酸盐 (PDS) 活化结合在碳纳米管 (CNT) 中空纤维膜上，采用了一种有效的策略来克服这一缺点。在酚类废水处理过程中，碳纳米管中空纤维膜不仅起到了分离屏障的作用，还起到了活化PDS及时降解微细苯酚的作用。与单一过滤 (33%) 相比，基于高级氧化功能 (AOF) 的膜在最佳条件下具有更高的苯酚去除率 (97%)：中性条件 (pH = 6)、0.5 mM PDS 和水力保留时间 (HRT) 为 39.6 秒。¹ O ₂ ) 通过自由基猝灭、电子顺磁共振 (EPR)、线性扫描伏安法 (LSV) 和开路电位模型。这些结果表明，这项工作在通过具有 AOF 的 CNT 中空纤维膜修复有机污染方面具有很高的前景。
