| titleOfInvention | Method for removing Cu ions from arsenic acid solution |
| abstract | Provided is a method for removing Cu ions from a solution containing arsenic acid (pentavalent As) and Cu ions while suppressing the reduction of the arsenic acid (pentavalent As) to arsenous acid (trivalent As) as much as possible. . In a arsenic acid solution containing Cu ions, ZnS is added in an amount equal to or less than 1.2 times the total molar amount of the Cu ions and reacted at 40 ° C. or higher to remove the Cu ions, or Add 1.0 equivalent or more of the total molar amount, and react at 40 ° C. or higher under oxygen blowing to remove the Cu ions.
