Uranium Extraction by Adsorption and the Types and Performance Enhancement Strategies for Adsorbents
摘要
Abstract
Controlling the use of fossil fuels and promoting the development of alternative new and clean energy sources is consistent with the theme of synergistic development between resource development and environmental protection.As a green energy source with high energy density,nuclear energy can be widely applied to alleviate the energy shortage in our country.The proven uranium resource content in seawater is more than 1 000 times higher than that in uranium mines.Extracting uranium from seawater is a potential way to ensure the long-term supply of uranium resource and the sustainable development of nuclear power.Adsorption has emerged as one of the effective methods for extracting uranium from seawater due to its advantages of high adsorption efficiency,simple operation,low cost,and environmentally friendly.However,the adsorption faces a number of challenges when extracting uranium from seawater,such as the extremely low concentrations of uranium in seawater and their stable existence in the form of Ca2UO2(CO3)3 or[UO2(CO3)3]4-,as well as a large variety and quantity of coexisting ions.Therefore,the preparation of high-performance adsorbents to achieve efficient and selective separation and enrichment of uranium in seawater is one of the important research topics in the field of environmental science.In this review,the types of adsorbents for uranium extraction from seawater and the performance enhancement strategies of their properties are briefly introduced,with the aim of helping researchers in this field design promising adsorbents for practical seawater uranium extraction.关键词
