Provided are a cobalt ion adsorption material which has a large adsorption capacity and which tends not to generate fine powder, and a method for producing the same. This cobalt ion adsorption material is a powder with a particle diameter of 100-1,000 μm, and contains 0.3-8.0 parts by mass of a binder constituted of a water-insoluble metal oxide or metal hydroxide fine particles with respect to 100 parts by mass of a cobalt adsorption main agent constituted of potassium hydrogen dititanate hydrate.

Cobalt ion adsorption material and method for producing same

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 KHO.2TiO.nHO (wherein x is 0.5 or more and 1.3 or less, and n is greater than 0), and no binder, wherein the particulate cobalt ion adsorbent has a particle size range of 150 μm or more and 1000 μm or less.
