|1. (WO2018101286) ADSORBENT CONTAINING AMORPHOUS IRON (III) HYDROXIDE AND METHOD FOR MANUFACTURING SAME|
|Applicants:||NIPPON CHEMICAL INDUSTRIAL CO., LTD.
|Title:||ADSORBENT CONTAINING AMORPHOUS IRON (III) HYDROXIDE AND METHOD FOR MANUFACTURING SAME|
Provided are: an adsorbent, containing iron (III) hydroxide, that can also be used upon being packed into a column, etc., and that has an excellent performance of adsorbing iodate ions in particular; and an industrially advantageous method for manufacturing the adsorbent. This adsorbent is characterized in containing an amorphous iron (III) hydroxide in which the temperature of a heat generation peak occurring on a DSC temperature rise characteristics curve for a 25-700°C temperature rise is 350-400°C, the weight decrease ratio when the temperature is raised from 25°C to 700°C is 18% or above, and the electrical conductivity is 14 mS/cm or below. The adsorbent preferably has a BET specific surface area of 100-300 m2/g and is more preferably a granulated product.
