| 目的 研究金属有机骨架材料MIL-101对气态碘单质的吸附与释放。方法 采用水热合成法合成金属有机骨架材料MIL-101，并利用X射线衍射（XRD）、扫描电子显微镜（SEM）、N2吸附脱附等温线等表征方法对合成的MIL-101样品进行表征。将制备的金属有机骨架材料MIL-101在75℃环境下对气态碘单质进行吸附，将吸附后的材料于无水乙醇溶液中进行碘单质的释放。结果 随着吸附时间的推移，金属有机骨架材料MIL-101对气态碘单质的吸附量逐渐升高，并于8h逐渐达到饱和吸附量2.61gI2/gMIL-101。MIL-101在无水乙醇溶液中随着时间的延长，材料吸附的碘单质渐渐释放出来。结论 MIL-101对气态碘单质在较高温度下有着优异的吸附效果，并表现出良好的循环使用性能，适合用于核电站蒸汽中放射性气态碘的吸附。 |

| Objective To study the adsorption and release of metal-organic framework MIL-101 for gaseous iodine. Methods Metal-organic framework MIL-101 was synthesized by hydrothermal synthesis method. The prepared MIL-101 was characterized by various techniques such as XRD, SEM, BET, TGA. Adsorption and release of the prepared metal-organic framework MIL-101 for gaseous iodine was carried out at 75℃. The absorbed material was dissolved in ethanol for iodine release. Results With the passage of the adsorption time, adsorption capacity of metal-organic framework MIL-101 for gaseous iodine was gradually increased and reached saturated adsorption capacity of 2.61gI2/gMIL-101 at 8h. With the passage of the time, iodine absorbed in the prepared material was gradually released. Conclusion The adsorption and release of metal-organic framework MIL-101 for gaseous iodine under high temperature has an excellent effect, and it can be recycled in the process of enrichment of iodine. So the material is suitable for the adsorption of radioactive gaseous iodide in the steam of nuclear power plant. |
