ABSTRACT OF THE DISCLOSURE Aqueous hydrogen peroxide solutions contain variable amounts of carbon compounds following their production by the so-called anthraquinone process. Various methods are known for separating out carbon compounds, including those using organic ion exchangers or macro-porous organic adsorber resins. However, there is a need for an improved process using an adsorption agent which can be regenerated without causing any problems. According to the invention, a zeolite from the set of dealuminized H-Y-zeolites with a (SiO2/Al2O3) modulus equal to or greater than 20 or H-mordenites with a modulus of at least 20 is used as the solid adsorption agent.
