Research progress on low-energy and high-efficiency electrochemical seawater uranium extraction systems
摘要
Seawater uranium extraction is of significant strategic importance for ensuring a continuous supply of uranium resources and the sustainable development of nuclear energy. However, the capacity, selectivity, and sustainability of this process have been notably impacted by factors such as the low concentration of uranium in seawater, the presence of complex competing ions, and inevitable marine interference. Over the past decade, substantial progress has been achieved in the development of materials and methods for uranium extraction. Notably, the electrochemical uranium extraction method has garnered widespread attention for its green, efficient, and modular development benefits. In this review, we summarize the latest advancements in the field of electrochemical uranium extraction. Firstly, we introduce the application of various electrochemical methods and different electrode materials in the extraction of uranium from seawater. Second, we analyze the mechanism of electrochemical uranium reduction and the existing new systems for uranium extraction. In the final part, we point out the limitations, challenges, and future prospects of electrochemical uranium extraction from seawater.
