A novel electro-peroxone membrane filtration (EPMF) system was constructed based on catalytic •OH production and enhanced mass transport with a flow-through, carbon nanotube (CNT) membrane cathode. Scanning electron microscopic and conductive atomic force microscopic characterization affirmed that the CNT membrane possessed a compact nano-porous structure with high electrical conductivity and large catalytic area. The EPMF system removed ibuprofen, a typical ozone-resistant pharmaceutical and personal care product, by 95.75 ± 1.12%, which was 3.72, 1.97 and 1.60 folds greater than those obtained in separate electrochemical filtration, and ozonation/peroxone-coupled filtration, respectively. Moreover, electron spin resonance in conjunction of quantitative •OH measurements showed that IBU degradation was mainly associated with advanced oxidation by in-situ produced •OH. The CNT cathode played a critical role in catalyzing H₂O₂ and O₃ decomposition, which synergistically promoted •OH formation during the EPMF process. These findings provided new insights into the applicability and mechanisms of EPMF for advanced drinking water treatment.

基于催化•OH 生产和通过流通式碳纳米管(CNT) 膜阴极增强的质量传输构建了一种新型电过氧酮膜过滤(EPMF) 系统。扫描电子显微镜和导电原子力显微镜表征证实了CNT膜具有致密的纳米多孔结构，具有高电导率和大催化面积。EPMF 系统将布洛芬（一种典型的抗臭氧药物和个人护理产品）去除了 95.75 ± 1.12%，分别是单独的电化学过滤和臭氧化/过氧酮耦合过滤的 3.72、1.97 和 1.60 倍。而且，电子自旋共振结合定量•OH 测量表明，IBU 降解主要与原位产生•OH 的高级氧化有关。CNT阴极在催化H₂ O ₂和O ₃分解，在EPMF 过程中协同促进•OH 的形成。这些发现为 EPMF 在高级饮用水处理中的适用性和机制提供了新的见解。
