Abstract
Official abstract text for this publication.
A cation adsorbent of an embodiment includes tungsten oxide particles having a BET specific surface area in a range of 0.82 m 2 /g or more and 820 m 2 /g or less. The cation adsorbent is added to a solution to be treated containing cations being recovery objects, and the cation adsorbent adsorbing the cations is precipitated. The generated precipitate is separated from the solution to recover the cations.
First claim
Opening claim text (preview).
What is claimed is: 1. A cation adsorbent, comprising: tungsten oxide particles having a BET specific surface area in a range of 0.82 m 2 /g or more and 820 m 2 /g or less, 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. 2. The cation adsorbent according to claim 1 , wherein a particle diameter of the tungsten oxide particle is in a range of 1 nm or more and 1000 nm or less. 3. The cation adsorbent according to claim 1 , wherein the tungsten oxide particles are dispersed in an aqueous dispersion medium.
