摘要:

控制化石能源的使用、促进可替代新能源和清洁能源的发展,符合资源开发与环境保护协同发展的主题。核能作为一种能量密度高的绿色能源,其广泛应用可缓解我国的能源短缺问题。已探明的海水中铀资源约为陆地铀矿的1 000倍,海水提铀是确保铀资源长期供应及核能可持续发展的潜在方法。吸附法因吸附效率高、操作简单、成本低和绿色环保等优点成为海水中铀酰离子提取的有效方法之一,但面临诸多挑战,如海水中铀酰离子的浓度极低且以Ca2UO2(CO3)3或[UO2(CO3)3]4-的形式稳定存在、共存离子种类和数量较多等。因此,制备高性能吸附剂是实现海水提铀的关键。综述了海水提铀吸附剂的类型及其性能强化策略,以期设计海水提铀吸附剂提供帮助。

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.
