摘要: 本文以甲基丙烯酸(MAA)和4-乙烯基吡啶(4-VP)为功能单体，乙二醇二甲基丙烯酸酯(EGDMA)为交联剂，异丙醇为溶剂，采用沉淀聚合的方法制备Pb(II)印迹聚合物。通过红外光谱(IR)对Pb(II)印迹聚合物的化学结构进行表征，利用扫描电镜(SEM)对印迹聚合物的外貌形态进行观察，BET分析仪检测其表面积以及原子吸收光谱(AAS)对Pb(II)印迹聚合物的选择性进行表征。结果表明Pb(II)印迹聚合物对水中的Pb(II)具有良好的吸附能力。
Abstract: In this paper, using methacrylic acid (MAA) and 4-vinyl pyridine (4-VP) as functional monomer, ethylene glycol 2-methylacrylate (EGDMA) as crosslinking agent, and isopropyl alcohol as the sol-vent, precipitation (II) imprinted polymer was prepared by Pb polymerization method. Through infrared spectroscopy (IR), chemical structure of Pb(II) imprinted polymers was characterized; by scanning electron microscopy (SEM), imprinted polymer appearance was observed; its surface area was detected by BET s analyzer; and with atomic absorption spectroscopy (AAS), the selectivity of Pb(II) imprinted polymers was characterized. The results show that Pb(II) imprinted polymer has good adsorption capacity for Pb(II) in water.
