《武汉工程大学学报》| 张雅萱 等:磁性超交联聚合物的制备及其对四环素的吸附

核心提示

中文摘要：

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。
