COBALT ION ADSORBENT, METHOD FOR PRODUCING SAME AND TREATMENT APPARATUS FOR COBALT ION-CONTAINING LIQUID

摘要

The present invention provides a particulate cobalt ion adsorbent which has a high adsorption capacity. A particulate cobalt ion adsorbent which contains potassium hydrogen dititanate hydrate represented by chemical formula K_2-xH_xO·2TiO₂·nH₂O (wherein x is from 0.5 to 1.3 (inclusive) and n is larger than 0), but does not contain a binder, while having a particle diameter range of from 150 μm to 1,000 μm (inclusive).
