摘要:
四环素的滥用所引起的过量排放严重威胁生态环境安全和人类健康。采用Friedel-Crafts烷基化反应制备得到了磁性超交联聚合物（Fe3O4@HCPs-PTES），并研究了其对四环素（TC）的吸附去除。系列表征表明，合成的Fe3O4@HCPs-PTES材料为结构松散，平均孔径和比表面积分别为2.9 nm和559 m2/g的多孔材料。吸附动力学和热力学研究发现，TC在Fe3O4@HCPs-PTES上的吸附符合双室一级动力学模型和Langmuir等温模型，其最大饱和吸附容量为493.7 mg/g，且该过程为自发、吸热过程；该吸附过程的作用力包括氢键、络合作用、π-π相互作用和孔隙填充。Fe3O4@HCPs-PTES材料具有良好的TC吸附能力、易于磁性回收以及可重复使用性，在废水处理方面应用前景广阔。
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.
