Provided is an adsorbent for iodide ions and iodate ions, which exhibits excellent adsorption performance of iodide ions and iodate ions. An adsorbent according to the present invention comprises cerium (IV) hydroxide and a poorly soluble silver compound. It is preferable that the content of the cerium (IV) hydroxide is from 50% by mass to 99% by mass (inclusive) and the content of the poorly soluble silver compound is from 1% by mass to 50% by mass (inclusive). It is also preferable that the poorly soluble silver compound is at least one substance that is selected from among silver zeolite, silver phosphate, silver chloride and silver carbonate. |
