AB  - The transition to clean energy and sustainable technologies necessitates securing precious metals, yet traditional land-based mining is increasingly unsustainable. Seawater holds immense potential as a mineral source, but its intricate ionic composition limits current extraction techniques. Here, we report a family of ion-exchangeable materials by grafting phosphate groups onto metal-organic framework glasses, followed by precise heat and aqueous treatments. This process introduces facile exchangeable ions and exposes active functional groups. Based on these structural features, the materials exhibit superior performance in selective recovery of magnesium and lithium from various natural seawater samples, surpassing a typical commercial resin in uptake rate, capacity, and recyclability. Our work presents a promising route for designing efficient adsorbents to extract valuable minerals from unconventional sources and help to secure the raw materials vital for a low-carbon future.
