    摘要: 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. Described is a process using a solid adsorption agent, which can be regenerated without causing any problems, whereby the carbon content is reduced. The solid adsorption agent is a zeolite from the set of dealuminised H-Y-zeolites with a (SiO.sub.2 /Al.sub.2 O.sub.3) ratio equal to or greater than 20 or H-mordenites with a (SiO.sub.2 /A1.sub.2 O.sub.3) ratio of at least 20.
