Owing to the poor treatment efficiency of wastewater containing fluoroquinolones (FQs), effective removal of such pollutants has become a significant issue in waste management. In this study, a ternary covalent organic polymer anchored with SOH (COP-SOH) was designed using the Schiff reaction and a multicomponent solvent thermal method. The synthesized COP-SOH polymer possesses multiple functional binding sites, including amide groups, sulfonic groups, and aromatic frameworks, enabling it to effectively adsorb ciprofloxacin (which belongs to FQs) through mechanisms such as pore-filling effects, electrostatic interactions, hydrogen bonding, π-π electron donor-acceptor (EDA) interactions, and hydrophilic-lipophilic balance. COP-SOH demonstrated outstanding adsorption performance for ciprofloxacin, exhibiting a high adsorption capacity, broad pH stability, strong resistance to ionic interference, and good regenerability. Moreover, it displayed preferential selectivity toward fluoroquinolone antibiotics. The present study not only investigates the intricate structural and functional design of COP-SOH materials but also presents potential applications for the efficient adsorption of specific antibiotics.
由于含氟喹诺酮类药物（FQs）废水的处理效率较差，因此有效去除此类污染物已成为废物管理中的一个重要问题。在这项研究中，采用席夫反应和多组分溶剂热法设计了一种带有 SOH 的三元共价有机聚合物（COP-SOH）。合成的 COP-SOH 聚合物具有多个功能结合位点，包括酰胺基、磺酸基和芳基骨架，使其能够通过孔填充效应、静电相互作用、氢键、π-π 电子供体-受体（EDA）相互作用和亲水-疏水平衡等机制有效吸附环丙沙星（属于 FQs）。COP-SOH 对环丙沙星表现出优异的吸附性能，具有高吸附容量、宽 pH 稳定性、强抗离子干扰能力和良好的可再生性。此外，它对氟喹诺酮类抗生素表现出优先的选择性。本研究不仅考察了 COP-SOH 材料的复杂结构和功能设计，还为特定抗生素的高效吸附提供了潜在应用。
