"Researchers estimate that seawater contains 4.5 billion metric tons, nearly 1,000 times more uranium that conventional sources. But, with existing technologies, we are far from extracting this element from seawater cost-effectively. Experts have said that uranium recovery from seawater is extremely challenging due to its very low concentration in comparison to the high abundance of interfering ions.
The team of researchers at IISER have developed a rare ionic macroporous metal-organic framework (MOF), which can effectively capture uranium. They managed to capture 96.3 per cent of uranium within two hours, which is in sharp contrast to the other existing adsorbent. A proper absorbent combining the features of high capacity, excellent selectivity, and ultra-fast kinetics has been a long challenge.

They collected seawater from the Arabian Sea (Juhu beach), Mumbai for uranium extraction and the absorbent resulted in a record uranium uptake capacity of 28.2 mg per gram in only 25 days and "satisfies the remarkable uranium extraction from seawater standard only in 2 days compared to existing adsorbents including commercially available materials reported so far."
