摘要
Abstract Since the environmental pollution posed by widely used sulfonamide antibiotics has been reported in natural aquatic system, designing novel adsorbents with excellent behaviors for adsorptive removal of sulfonamide antibiotics becomes a critical challenge in remediation management. Herein, two three‐component hybrid covalent organic polymers were successfully developed through a facile room‐temperature solution‐suspension method based on dynamic covalent Schiff‐base chemistry and used to remove a typical sulfonamide antibiotic [sulfadiazine (SDZ)] from aqueous solution. The 1,3,5‐triformylphloroglucinol (TFP) and benzene‐1,3,5‐tricarbohydrazide (BTCH) reacted with benzidine (BD) (JLUE‐COP‐26) and exhibited a good adsorption capacity for SDZ, followed by the reaction of TFP, BTCH and p ‐phenylenediamine (PDA) (JLUE‐COP‐25). Moreover, the adsorption data of SDZ by two JLUE‐COPs were analyzed to be pseudo‐second‐order kinetic representable and Langmuir adsorption model fitted. In addition, the possible underlying mechanisms were proposed as a combination of porous feature, electrostatic force, hydrophobic interaction, π‐π stacking and hydrogen bonding interaction.
