Claim Text:
1. A cation adsorbent, comprising: tungsten oxide particles having a BET specific surface area in a range of 0.82 m wherein a cation to be adsorbed by the cation adsorbent is at least one ion selected from the group consisting of a cesium (Cs) ion and a strontium ion (Sr), and an adsorption ratio of at least one ion selected from the group consisting of the cesium (Cs) ion and the strontium (Sr) ion is higher than an adsorption ratio of at least one ion selected from the group consisting of a magnesium (Mg) ion, a calcium (Ca) ion, and a potassium (K) ion under an environment in which at least one ion selected from the group consisting of the magnesium (Mg) ion, the calcium (Ca) ion, and the potassium (K) ion exists together.
