海水提铀吸附材料研究进展

Research progress on adsorption material for U extraction from seawater

在清洁能源中,核能将在全球范围内持续增长,特别是在中国、俄罗斯和其他一些国家。由于陆地铀资源非常有限,而海水中铀含量非常高,因此从海水中提取铀是全世界科研工作者的研究热点,也成为人类能源可持续发展的重要保证。然而,目前来看,海水提铀吸附材料仍然存在生物污染、吸附率低、竞争性金属离子共存、材料可重复使用率低等问题,导致相关技术难以推广应用。针对如何开发出成本低、吸附率高、选择性高、抗污染的海水提铀吸附材料,总结了近年来比较热门的相关研究,并进行探讨比较,对海水提铀中存在的问题和未来研究方向进行了总结和展望。

Among clean energy,nuclear energy will continue to grow globally,especially in China,Russia and some other countries.Because terrestrial uranium(U)resources are very limited,and the U content in seawater is very high,extracting U from seawater is a research hotspot for researchers all over the world,and it has also become an important guarantee for the sustainable development of human energy.However,currently,adsorption materials for U extraction from seawater still have problems such as biological pollution,low adsorption rate,coexistence of competitive metal ions,and low material reusability,making it difficult to promote related technologies.Aiming at how to develop adsorption materials for U extraction from seawater with low cost,high adsorption rate,high selectivity and antipollution,the relevant researches that have been popular in recent years were summarized,discussed and compared,and summarized the problems existing in the extraction of U from seawater and future research.The direction was summarized and prospected.
