Humans only got a limited number of natural resources to survive and exploit. Water, as one of the limited natural resources, has been polluted because of human rapid development in many fields of industries. Nuclear wastes, as one of the pollutants, bring serious or in-reversible harm not only to the environment but also to human health. Metal-organic frameworks (MOFs) materials could be applied to various kinds of areas and also got a huge potential in the treatment of wastewater with radioactive wastes. This article mainly talks about the research progress of MOF material used in the field of radioactive wastewater treatment and introduces the preparation and characteristics of MOF-5, HKUST-1/KCoFC, and UiO66-COOH materials. Additionally, factors including solid-liquid ratio, initial concentration, reacting time, and pH value that affect the adsorption capacity on U(VI), Cs, and Sr are analyzed. Some research on MOFs materials used to remove different kinds of radioactive substances is also highlighted. Finally, some problems that still exist are raised, and expectations and directions for future development in this field are provided.
