摘要：

Adsorption has proven to be the most convenient, simple, and valid method for extracting uranium from seawater. The research challenge is synthesizing an ideal adsorbent with high adsorption capacity, a solid structure, high activity, and good chemical stability that can adapt to a harsh seawater environment. Porous organic frameworks (POFs) stand out among many adsorbents with high surface area and particular porosity structure. Thus, compared with other conventional adsorption materials (such as carbon, zeolite, etc.), POFs have unique advantages in adsorptive separation and selective catalysis and can effectively capture uranium from the seawater. This review systematically and comprehensively summarizes the research developments on POF application in uranium extraction from seawater. The survey also comprehensively explains and illustrates POF properties, typical synthesis methods, and compounding with other adsorbents to improve the adsorption performance of their composites. Finally, the review suggests future research directions that will contribute to promoting and applying POFs for seawater uranium extraction, stressing the importance of these suggestions for guiding future research in this field. © 2024 Elsevier B.V.
