  • 摘要: 研究以UiO-66为稳定粒子，阿莫西林（AMOX）为模板分子通过皮克林乳液法制备分子印迹中空微球（MIHM），并用于分离富集溶液中的阿莫西林.通过SEM、FT-IR和XRD等方法和静态吸附实验对MIHM的理化性质和吸附性能进行研究.结果表明，UiO-66纳米粒子能够稳定皮克林乳液，粒子分布于中空MIHM胶囊表面，胶囊粒径约为20-60 μm.吸附实验结果表明，MIHM对AMOX有较大的吸附容量，吸附容量在318 K，100 mg·L-1的AMOX溶液中达到0.1376 mmol·g-1，在选择性吸附实验中对AMOX具有选择性识别性能.经过3次循环回用后材料吸附容量降低12.71%，有良好的再生性.
    Abstract: Molecular-imprinted hollow microspheres (MIHM) were prepared by Pickering emulsion method using UiO-66 as stable particles and amoxicillin (AMOX) as template molecule, and were used to separate and enrich amoxicillin in solution. The physicochemical properties and adsorption properties of MIHM were studied by means of SEM, FT-IR, XRD and static adsorption experiments. The results indicated that UiO-66 nanoparticles could stabilize Pickering emulsion, and the particles were distributed on the surface of hollow MIHM capsules. The diameter of the capsules was about 20-60 μm. The results of adsorption experiments showed that MIHM obtained a large adsorption capacity for AMOX. The adsorption capacity reached 0.1376 mmol·g-1 in 318 K and 100 mg·L-1 AMOX solutions. MIHM had selective recognition performance for AMOX in selective adsorption experiments. After three recycling cycles, the adsorption capacity of the material decreased by 12.71%, and the material possessed good regenerability.
