Description
Lijun Hu and co-authors build a modified fiber that pulls uranium from seawater in this 2024 study. The oceans hold vast uranium, but at vanishing low levels. Fibrous adsorbents are seen as the most promising way to harvest it.
Their fiber starts from a tough polyethylene base, reshaped by radiation grafting. A branched helper layer speeds uranium ions through the fiber's depths. The design also resists fouling by sea life, a common failure. In lab solution the fiber loaded far more uranium than in fake seawater tests. A month-long seawater trial gives the realistic rate. Such fibers could one day make ocean uranium a real fuel source.
