A process for producing a purified aqueous hydrogen peroxide solution comprising bringing an aqueous hydrogen peroxide solution containing impurities into contact with an anion exchange resin in the fluoride form is disclosed. n According to the process, impurities in the aqueous hydrogen peroxide solution, particularly impurities containing silicon, such as silicates and silicic acid, can efficiently be removed, and a purified aqueous hydrogen peroxide solution having a high purity can be obtained. |
