海水提铀的最新进展

New development of uranium extraction from sea water

基于铀的战略价值和铀矿资源的有限性,从海水中提取铀作为传统矿石型铀资源的补给,对支持我国核电产业的快速发展具有重要意义。综述了近年来开发的海水铀回收材料,包括合成聚合物吸附剂、无机吸附剂和纳米结构材料等,指出了当前从海水中提取铀所面临的主要挑战。同时,介绍了国内外实际海水提铀的工业化研究进展以及铀的后处理研究,并对今后的海水提铀工作进行了展望。

Based on the strategic value of uranium and the limited nature of uranium mineral resources,the extraction of uranium from seawater as a recharge of traditional ore-type uranium resources is of great significance to support the rapid development of China’s nuclear power industry.This review comprehensively surveys recent development materials for extracting uranium from seawater,including synthetic polymer adsorbents,inorganic adsorbents and nanostructured materials,and points out the main challenges in extracting uranium from seawater.Furthermore,this paper also introduces the industrial research progress of practical uranium extraction from seawater,as well as the research on the reprocessing of uranium.
