磁性超交联聚合物的制备及其对四环素的吸附
Preparation of magnetic hyper-crosslinked polymer and its adsorption for tetracycline
摘要
Abstract
Excessive discharge of tetracycline resulting from its misuse poses a serious threat to ecological safety and human health.In this study,a magnetic hyper-crosslinked polymer(Fe3O4@HCPs-PTES)was synthesized via Friedel-Crafts alkylation and employed for the adsorptive removal of tetracycline(TC)from aqueous solutions.Comprehensive characterization revealed that the as-synthesized Fe3O4@HCPs-PTES exhibited a loose porous structure with an average pore size of 2.9 nm and a specific surface area of 559 m²/g.Adsorption kinetics and isotherm studies demonstrated that TC adsorption onto Fe3O4@HCPs-PTES followed the two-compartment first-order kinetic model and the Langmuir isotherm model,with a maximum adsorption capacity of 493.7 mg/g.Thermodynamic analysis indicated that the adsorption process was spontaneous and endothermic.The adsorption mechanism involved multiple interactions,including hydrogen bonding,complexation,π-π stacking,and pore filling.Benefiting from its excellent adsorption capacity,facile magnetic separability,and good reusability,Fe3O4@HCPs-PTES exhibits considerable potential for application in wastewater treatment.关键词
