海水提铀用偕胺肟基纤维吸附材料的研究进展

Research Progress of Amidoxime-Based Fiber for Uranium Extraction From Seawater

铀是发展核能不可或缺的重要元素。因陆地铀储量有限而通过海水提铀能够有效解决这一问题。研究发现偕胺肟基(AO)吸附材料对铀酰离子的吸附性能优异。本文总结了国内外对AO基纤维吸附材料的研究进展,分析了AO基纤维吸附材料的制备方法和吸附性能,同时也分析了该类材料的发展进程与走向,对目前AO基纤维吸附材料工业化存在的问题进行了讨论,最后对未来海水提铀的发展进行了展望。

Uranium is an indispensable element for the development of nuclear energy.Uranium extraction from seawater can effectively solve the problem of the shortage in land uranium mines.Amidoxime(AO)-based adsorbents exhibit excellent adsorption performance for uranyl ions.This article reviews the research progress of AO-based fiber since it has been reported,analyzes the preparation method and adsorption performance of AO-based fibrous adsorbent,and studies the development process and trend of this type of materials.Furthermore,the existing issues of the current industrialization of AO-based fibrous materials is discussed.Finally,the development of uranium extraction from seawater in the future is prospected.
