摘要：
A purified aqueous solution of hydrogen peroxide is produced by contacting an aqueous solution of hydrogen peroxide containing organic impurities with a hydrophilic porous resin (the product under a tradename "WOFATIT EP63", etc.) having a specific surface area of not less than 800 m.sup.2 /g to remove the organic impurities in the aqueous solution of hydrogen peroxide.
