通过种子乳液聚合结合开环反应制备了β-环糊精(β-CD)功能化磁性复合微球 Fe3 O4@PG-CD。通过红外光谱(FT-IR)、透射电镜(TEM)、动态光散射仪(DLS)、热重分析(TGA)仪对 Fe3 O4@PG-CD 进行了系统的表征。考察了 Fe3 O4@PG-CD 对模型环境污染物双酚A(BPA)的吸附性能,结果表明,Fe3 O4@PG-CD对 BPA 具有良好的吸附去除能力,其饱和吸附容量为39.68 mg/g。所开发的磁性复合微球材料可望成为一种新型吸附分离载体。
β-cyclodextrin (β-CD)functionalized magnetic composite microspheres (Fe3 O4@PG-CD)were pre-pared by the combination of seeded emulsion polymerization and subsequent ring-opening reaction of epoxy groups.The as-prepared Fe3 O4@PG-CD are systematically characterized by infrared (IR)instrument,trans-mission electron microscope (TEM),dynamic light scattering (DLS)instrument,thermogravimetric analysis (TGA)instrument.Moreover,the adsorption property of Fe3 O4@PG-CD for model of environmental pollu-tants,biphenol A (BPA)was also investigated.The experimental results showed that the Fe3 O4@PG-CD have an excellent adsorption capacity for BPA,the maximum adsorption capacity was 39.68 mg/g.The magnetic composite microspheres developed in this study could serve as a novel separation carrier.
