Abstract
A cation adsorbent of an embodiment includes tungsten oxide particles having a BET specific surface area in a range of 0.82 m2/g or more and 820 m2/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.
