Abstract
Uranium is recovered from its solution through contact with a uranium-recovering material of higher resistance to water and higher mechanical strength comprising a weakly basic anion exchange resin having pyridine nuclei at its main chain or side chain, and a crossed-linked polymer structure with a high uranium selectivity at a high uranium-adsorbing speed.
