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.
A particulate cobalt ion adsorption material comprising 0.3 parts by mass or more and 8.0 parts by mass or less of a binder consisting of fine particles of a water-insoluble metal oxide or metal hydroxide with respect to 100 parts by mass of a cobalt ion adsorption main agent consisting of potassium hydrogen dititanate hydrate, wherein the particulate cobalt ion adsorption material has a particle size of 100 μm or more and 1000 μm or less.
