摘　　要：通过在聚苯乙烯阴离子交换剂D201内合成UIO-66,制备复合吸附剂D201@UIO-66,用来去除水体药物污染。这种方法提高了金属有机骨架在液体中的结构稳定性并增强了吸附性能。通过XRD、SEM、EDS、FT-IR、BET等方式对复合吸附剂进行表征,结果表明,在D201中成功负载UIO-66。批量吸附实验表明,当复合吸附剂的用量为0.5 g·L^(-1)时,复合吸附剂的最大实验吸附量为142.5 mg·g^(-1)。复合吸附剂在较宽pH范围内体现出吸附稳定性。在其他阴离子的干扰下,复合吸附剂仍对阿洛西林钠具有选择吸附性。吸附动力学过程与伪二级动力学吸附模型符合,吸附等温线与Langmuir模型更为符合。In this study,a composite adsorbent D201@UIO-66 was prepared by synthesizing UIO-66 within a polystyrene anion exchanger D201 and used to remove pharmaceutical contamination from water bodies.This approach improved the structural stability of the metalorganic backbone in the liquid and improved the adsorption performance.The composite adsorbent was characterized by XRD,SEM,EDS,FT-IR and BET,and the results showed that UIO-66 was successfully loaded in D201.The batch adsorption experiments showed that the maximum experimental adsorption capacity of the composite adsorbent was 142.5 mg·g^(-1) when the amount of composite adsorbent was 0.5 g·L^(-1).The composite adsorbent exhibited adsorption stability over a wide pH range.The composite adsorbent showed selective adsorption of sodium aloxacillin in the presence of other anions.The adsorption kinetics were consistent with the pseudo-secondary kinetic adsorption model,and the adsorption isotherms were more consistent with the Langmuir model.The composite adsorbent D201@UIO-66 has good potential for the adsorption of pharmaceutical contamination in water.
