IODATE ION ADSORBENT AND METHOD FOR PRODUCING SAME

WIPO Patent Application WO/2016/035839

A1

The present invention provides an iodate ion adsorbent which has excellent iodate ion adsorption performance. An iodate ion adsorbent according to the present invention contains a cerium hydroxide (IV). The cerium hydroxide (IV) has a weight loss rate of from 4.0% to 10.0% (inclusive) if the temperature thereof is increased from 200°C to 600°C in a thermogravimetric analysis. In addition, if the cerium hydroxide (IV) is subjected to an infrared absorption spectrum analysis, absorption peaks are observed in the range from 3,270 cm-1 to 3,330 cm-1 (inclusive), in the range from 1,590 cm-1 to 1,650 cm-1 (inclusive) and in the range from 1,410 cm-1 to 1,480 cm-1 (inclusive).
