金属有机框架材料吸附放射性碘废气研究进展

Research Progress on the Adsorption of Radioactive Iodine Exhaust by Metal-Organic Framework Materials

随着核工业的发展,放射性碘被确定为最危险的核废料之一。放射性碘废气的吸附对于降低核污染也有着重要意义。金属有机框架(MOFs)是一种由无机金属中心(如金属离子或金属簇)与桥连的有机配体通过自组装相互连接形成的晶态多孔材料,因其多孔性和高比表面积等特点,MOFs被认为是理想的碘吸附材料。简要论述近年对于不同金属中心的MOFs在碘吸附方面的进展,探讨MOFs复合材料对放射性碘的吸附能力,展望高效放射性碘吸附MOFs材料未来的发展形势。

With the development of the nuclear industry,radioactive iodine has been identified as one of the most dangerous nuclear waste materials.The adsorption of radioactive iodine waste gas is also important for reducing nuclear pollution.Metal-Organic Frameworks(MOFs) are a kind of porous crystal material formed by the self-assembly and interconnection of inorganic metal centers(such as metal ions or metal clusters) and bridged organic ligands.Due to their porosity and high specific surface area,MOFs are considered as ideal iodine adsorption materials.This article mainly reviews the research progress of MOFs materials in the field of iodine adsorption.Firstly,it briefly discusses the progress of different metal-centered MOFs in iodine adsorption in recent years.Secondly,it explores the adsorption capacity of MOFs composite materials for radioactive iodine.Finally,it looks forward to the future development trend of efficient radioactive iodine adsorption MOFs materials.
