| 中文摘要: |
| 利用分子印迹技术制备了重金属镉(II)的印迹聚合物，并对其识别性能进行定量描述.以镉(II)离子为模板，安息香肟为功能单体，乙二醇二甲基丙烯酸酯为交联剂，偶氮二异丁腈为引发剂，采用本体聚合法制备印迹聚合物.实验结果表明，与未印迹的聚合物相比较，印迹聚合物对镉(II)离子具有较好的识别选择性，达到吸附平衡的时间为50 min，初始浓度为10 mg/mL时，吸附量为2.12 mg/g，并推测了该印迹聚合物和镉离子的识别机理. |
| 英文摘要: |
| A novel type ion imprinted polymer (IIP) was prepared by molecular imprinting technology (MIT).The selectivity and adsorption capacity for the Cd(II) ions of Cd(II)-MIP were systematically studied in this paper.The IIP was prepared by bulk polymerization using Cd(II) ion as a template,α-benzoin oxime as a functional monomer and ethylene glycol dimethacrylate (EGDMA) as a crosslinker.The results obtained show that,in comparison with non-imprinted polymer,the sorption equilibrium was achieved in 50 min and the maximum sorption of Cd(II) imprinted polymer was about 2.12 mg/g.The mechanism for the adsorption of Cd(II) on the imprinted polymers were investigated. |
