Abstract:

Uranium is the most significant element in the nuclear industry and is widely used in nuclear fuels as well as nuclear weapons. At present, the total amount of uranium discovered on land is less than 5 million tons, which makes it essential to exploit uranium resources in seawater. Adsorption, as the most promising method for uranium extraction from seawater, has been widely studied in the preparation of various adsorbents, the mechanism of adsorption, and the various problems encountered in natural seawater. In this paper, the continuous research conducted in recent years on uranium extraction from seawater, including material preparation methods, adsorption mechanisms, adsorption technology, and natural seawater adsorption, was summarized. Although uranium extraction from seawater has been studied since the 1960s, the experimental results for natural seawater show that some key problems, such as the preparation of highly efficient adsorption materials, still need to be solved.

Key words: Uranium extraction from seawater, Adsorbent material, Coordination mechanism
