随着人类越来越多地使用放射性核素,放射性核素废料会对环境造成一定的威胁,并最终对人群健康造成危害.金属-有机骨架(metal-organic frameworks,MOFs)材料作为一种新型材料由于具有比表面积大、孔隙度高及结构多样性等特点而广泛应用于气体吸附存储、催化、光学元件、传感、色谱分离和生物医学等领域.目前,将MOFs材料用于放射性核素的吸附开始引起放射化学与环境科学家的广泛兴趣.本文综述了MOFs材料用于部分放射性核素吸附的研究进展,包括MOFs合成方法、特性以及用于碘、氙、铀及钯等放射性核素的吸附分离,并对MOFs材料用于吸附放射性核素的前景进行了展望.
With the increasing use of radionuclides by human beings, radionuclide waste poses a certain environmental threat and eventually endangers the health of the population.As a new type of metal-organic frameworks (MOFs) material, Materials are widely used in the field of gas storage, catalysis, optics, sensing, chromatographic separation and biomedicine due to their large specific surface area, high porosity and diversity of structures etc. At present, MOFs materials are used in radionuclides Has attracted a great deal of interest from radiochemistry and environmental scientists.In this paper, the recent advances in MOFs materials for partial radionuclide sorption have been reviewed, including the synthesis methods and properties of MOFs and their applications in radionuclides such as iodine, xenon, uranium and palladium Adsorption and separation, and prospects for the MOFs materials for the adsorption of radionuclides prospects.
