Process for producing a purified aqueous hydrogen peroxide solution

摘要

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. 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.
