Abstract

The rising presence of ibuprofen (IBP) in natural water bodies, restricting from its widespread pharmaceutical usage, necessitates effective remediation strategies. This study introduces IB-COF, a novel covalent organic framework synthesized via a solvothermal method, specifically engineered for IBP extraction from aqueous solutions. IB-COF showcases remarkable adsorption performance, achieving equilibrium within 60 min with a capacity of 512 mg/g, outperforming conventional adsorbents. Its adsorption kinetics align with pseudo-second-order and Langmuir models, indicating efficient monolayer adsorption. Significantly, IB-COF exhibits robust recyclability over five cycles. Among the prevalence of IBP contamination, IB-COF demonstrates promise in selectively extracting IBP even in the presence of competing pharmaceuticals. Overall, our findings underscore the potential of IB-COF as an advanced adsorbent for mitigating IBP pollution in water sources, contributing significantly to environmental purification efforts and water pollution mitigation strategies.

利用 IB-COF 共价有机框架去除水中的布洛芬

布洛芬（IBP）在天然水体中的含量不断增加，限制了其在医药方面的广泛应用，因此有必要采取有效的补救策略。本研究介绍了一种新型共价有机框架 IB-COF，它是通过溶热法合成的，专门用于从水溶液中萃取 IBP。IB-COF 具有卓越的吸附性能，可在 60 分钟内达到平衡，吸附容量为 512 mg/g，优于传统吸附剂。其吸附动力学符合伪二阶和 Langmuir 模型，表明其具有高效的单层吸附能力。值得注意的是，IB-COF 在五个循环周期内表现出很强的可回收性。在 IBP 污染普遍存在的情况下，IB-COF 显示出选择性提取 IBP 的前景，即使在存在竞争药物的情况下也是如此。总之，我们的研究结果强调了 IB-COF 作为一种先进吸附剂在减轻水源中 IBP 污染方面的潜力，它将为环境净化工作和水污染缓解战略做出重大贡献。
