摘　　要：随着我国工业的快速发展,重金属、放射性金属污染变的尤为严重,这些金属一旦进入了土壤和水体中,将会对环境造成极大的破坏。它们可以在水体中被水生生物富集,也可以在土壤中被植物吸收,从而通过食物链的传递到人体中,对人的身体健康造成极大的危害。金属-有机骨架(metal-organic frameworks,MOFs)材料是一种比表面积大、孔隙度高、种类多样性、结构可调控等优点的化合物,已成为各学科的研究热点。但相对应用于储备气体来说,MOFs材料用于吸附有害金属的研究还是比较少的,尤其是应用于放射性金属的吸附研究。本文综述了近年来MOFs作为吸附有害金属材料的研究进展,对MOFs材料的合成方法、孔径结构、晶型结构及其对吸附有害金属的吸附条件做了深刻的剖析,并对MOFs材料用于吸附有毒有害金属的前景进行了展望,以期为MOFs材料吸附有害金属的应用提供一定的借鉴和参考。With the development of China＇s industry,heavy metal and radioactive metal cause serious environmental pollutions,once these metals in soil and water,it will cause great damage to the environment,they can be enriched in aquatic organisms in water and can be absorbed by plants in the soil,however,it will pass through the food chain to the human body and will cause great harm to human health. Metal- organic frameworks（ MOFs） is a new class of nanoporous materials with large surface area,high porosity,various topologies,as well as acceptable adjustable pore size,it has become a hot research topic in various disciplines now. But the relative application in gas reserves,MOFs material for the adsorption of harmful metals is still relatively small,especially used in adsorption of radioactive metals. In this paper,the research progress of MOFs as adsorption harmful metal in recent years is detailedly reviewed,in addition,detailed analysis of the effect of synthetic method,pore structure,crystal structure,framework charge and functional group on adsorptions provided. Besides the research trend to the treatment of the adsorption harmful metal in the future was discussed as well and in order to provide a reference for application of the adsorbent material in the future.
