| 中文摘要: |
| 合成胺乙基β-环糊(6-EA-β-CD)和磺酰化β-环糊精(6-OTs-β-CD),以磺酰化β-环糊精和胺乙基β-环糊精为原料在特定条件下合成桥联β-环糊精,并采用红外光谱、核磁共振光谱、元素分析进行检测,验证合成产物的可靠性.采用扫描电镜分析合成材料的外部形貌.在不同条件下研究桥联β-环糊精对钍离子的吸附性能.结果表明,室温下20 mg桥联β-环糊精在溶液pH为4、震荡吸附60 min对钍达到吸附平衡,吸附容量为10.49 mg/g. |

| Prepare mono-6-O-aminoethyl-β-cyclodextrin(6-EA-β-CD) and mono-6-O-(p-toluenesulfonyl)-β-cyclodextrin (6-OTs-β-CD).The ethylamine-bridged β-cyclodextrins was synthetized by 6-OTs-β-CD and 6-EA-β-CD under specific conditions.FTIR,NMR spectroscopy and elemental analysis were employed to confirm the reliability of the newly synthetic bis(β-cyclodextrin).Scanning electron microscope was used to characterize the surface morphology of the material.Study on bridged β-cyclodextrins’s adsorption properties of Thorium ions under different conditions.Experiments show that:the adsorption of thorium using the material prepared can achieve equilibrium within 60 minutes at room temperature under the condition of pH=4,the adsorption capacity is 10.49 mg/g. |
