摘要:

多孔芳香框架材料是一类新兴的有机多孔纳米材料,具有稳定性高、比表面积大、易于修饰改性等特点,可以满足多种吸附材料设计的需求。近几年众多学者将修饰改性后的多孔芳香框架材料应用于海水提铀,发现其具有较大的铀吸附量、优异的铀选择性、良好的可循环性等特点。本文综述了近年来基于海水提铀的多孔芳香框架材料的研究进展,首先简要介绍了其合成反应与合成技术,然后分类讨论了与铀的相互作用机理,并评估了多种改性多孔芳香框架材料对铀的吸附性能,分析了其对铀的高选择性和高吸附效率的原因。最后,本文针对目前多孔芳香框架材料在海水提铀中的局限性(多孔芳香框架材料的合成、吸附性能的提高、成本的降低及机理的深层次研究等)为未来设计低成本高性能的多孔芳香框架材料吸附剂提供了几点建议。

Abstract:

Porous aromatic framework materials are an emerging class of organic porous nanomaterials with high stability, large specific surface area and easy modification, which can meet the needs of various adsorption material designs. In recent years, many scholars have applied the modified porous aromatic framework materials in uranium extraction from seawater and found that they have large uranium adsorption capacity, excellent uranium selectivity and good recyclability. This paper reviews the recent research progress of porous aromatic framework materials based on uranium extraction from seawater. The synthetic reactions and synthesis techniques of porous aromatic framework materials are firstly briefly introduced, and then their interaction mechanisms with uranium are categorically discussed. The adsorption performance of various modified porous aromatic framework materials on uranium are evaluated, and the reasons for the high selectivity and high adsorption efficiency on uranium are analyzed. Finally, the paper provid some suggestions for the future design of low-cost and high-performance porous aromatic framework adsorbents in view of the current limitations of porous aromatic framework materials for uranium extraction from seawater (synthesis of porous aromatic framework materials, improvement of adsorption performance, cost reduction and in-depth study of the mechanism, etc.).

Key words: porous aromatic framework, uranium extraction from seawater, adsorbents, synthesis, nanomaterials
