Abstract

CoFe₂O₄-PES photocatalytic membranes were assessed for Naproxen degradation in water. The degradation obeyed first-order reaction kinetics (K_app: 1.25 × 10⁻³ min⁻¹ - 3.90 × 10⁻³ min⁻¹). Surface roughness altered the collision dynamics of reactive species. It enhanced the chances of successful collision between Naproxen and reactive radicals. Membrane hydrophilicity improved the generation of reactive radicals by minimizing the blockage of active sites. Intermediates detected by Quadrupole Time-of-Flight Mass Spectrometry showed that Naproxen degraded via demethylation, hydroxylation, and ring-opening reactions. Leaching studies investigated the stability of the prepared membranes. CoFe₂O₄-PES membranes can be used in advanced oxidation technologies for water treatment.

利用钴铁氧体光催化膜修复水溶液中的非甾体抗炎药物

对 CoFe2O4-PES 光催化膜在水中降解萘普生的情况进行了评估。降解遵循一阶反应动力学（Kapp：1.25 × 10-3 min-1 - 3.90 × 10-3 min-1）。表面粗糙度改变了反应物的碰撞动力学。它提高了萘普生与活性自由基碰撞成功的几率。膜的亲水性可最大限度地减少活性位点的阻塞，从而改善活性自由基的生成。四极杆飞行时间质谱法检测到的中间产物表明，萘普生是通过去甲基化、羟基化和开环反应降解的。浸出研究调查了所制备膜的稳定性。CoFe2O4-PES 膜可用于水处理的高级氧化技术。
