Claim 3:
4. A method for producing the particulate cobalt ion adsorbent comprising potassium hydrogen dititanate hydrate represented by chemical formula K2-xHxO.2TiO2.nH2O 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, comprising subjecting potassium dititanate represented by chemical formula K2O.2TiO2 to hydration and cation exchange between potassium ions (K+) and protons (H+) to obtain potassium hydrogen dititanate hydrate represented by chemical formula K2-xHxO.2TiO2.nH2O wherein x is 0.5 or more and 1.3 or less, and n is greater than 0, and granulating the potassium hydrogen dititanate hydrate without using a binder.
