| 目的 改进并提高MIL-101(Cr)吸附气态碘单质的性能，以期用于核事故放射性碘富集吸收。方法 通过水热法制备MIL-101(Cr)材料，并利用纳米Fe掺杂改性，运用SEM、XRD等对掺杂前后的材料进行表征。将材料在75 ℃条件下对气态碘单质进行吸附，并比较不同Fe掺杂量下材料对气态碘吸附性能的差异。结果 纳米Fe成功掺杂于基体材料MIL-101中，并对基体材料晶体结构无破坏作用。吸附性能研究表明，掺杂纳米Fe质量分数为1%的Fe@MIL-101吸附性能最优，对气态碘的饱和吸附量可达3.42 g(I2)/g(MIL-101)。结论 纳米Fe掺杂改性的MIL-101材料在高温条件下对气态碘单质具有良好的吸附效果，有望应用于核反应堆事故中对放射性碘的富集或捕集。 |

| Objective To improve the adsorption performance of metal organic frameworks material MIL-101 for gaseous iodine. Methods The Fe-doped modified MIL-101 material was prepared by hydrothermal synthesis method, and the materials were characterized and analyzed by scanning electron microscopy (SEM) and X-ray diffraction (XRD). The adsorption experiment of the materials was carried out at 75 ℃. And the comparison on the adsorption properties of materials was taken under different Fe doping levels. Results The nano-Fe was successfully doped in the substrate MIL-101 and had no damage effect to the crystal structure of the substrate material. According to the research on absorption property, when the Fe-doped mass fraction was 1%, the adsorption ability was the best and its saturated adsorption capacity could reach 3.42 g(I2)/g (modified material). Conclusion The Fe-doped modified materials have an excellent adsorption performance at high temperatures, and can be applied for enrichment and trapping of radioactive iodine of reactor accidents. |
