  • Patent number: 8802590
    Abstract: An indium adsorbent is provided that is obtained by the following process. A hydrophilic polymer having a carboxyl group in which indium is incorporated in advance is caused to absorb an aqueous solution of a water-soluble monomer, a cross-linking agent, and a polymerization initiator, and an acid treatment is performed on a polymer obtained by polymerizing the water-soluble monomer, to obtain the indium adsorbent. The indium adsorbent has a template architecture with respect to indium. Accordingly, the indium adsorbent is capable of adsorbing indium with a high selectivity. An indium selection rate is 2.0 or more with respect to zinc.
