| titleOfInvention | Method for treating selenium compound-containing water using an adsorption material for heavy metal-containing anions |
| abstract | An object of the present invention is to provide a method for treating an aqueous solution containing a selenium compound selectively, which can reliably remove these ions from an aqueous solution coexisting as selenite ions and / or selenite ions. SOLUTION: Water containing a selenium compound is mixed with a heavy metal-containing anion adsorbing material made of a fine powder resin containing a carboxyl group to which iron ions are adsorbed, and the selenium compound is adsorbed on the resin. The method for treating an aqueous solution containing a selenium compound, which comprises separating the resin fine powder after the separation, wherein selenate ions and selenite ions dissolved in the aqueous solution containing the selenium compound A method for adsorbing toxic substance ions such as selenate ions and selenite ions by adsorbing and removing carboxyl groups in the resin as an adsorbing material and adsorbing iron ions to the carboxyl groups. It is. [Selection diagram] Fig. 1 |
