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

Abstract

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.
