Biochar Material Unlocks Uranium Recovery from Seawater

Biochar Editorial Office, Shenyang Agricultural University

Researchers have developed a new biochar-based composite that can capture uranium from water while also converting part of it into a less toxic chemical form, offering a potential strategy for recovering uranium from seawater and supporting future nuclear energy resources.

Uranium is a key fuel for nuclear power, but land-based uranium reserves are unevenly distributed and limited. Seawater contains an enormous amount of dissolved uranium, estimated to be roughly 1,000 times greater than the reserves found in terrestrial ores. However, extracting uranium from seawater remains difficult because uranium occurs at very low concentrations and must be selectively separated from many competing ions.
