 ein Saugfilter ab,   wo @die Barinmnitratkristalle vom flüssigen Wasserstoffsuperoxyd ge-   trennt werden. In dieses   Wasserstoffsuperänd,   in dem sich die ursprünglich zugesetzte Phospliorsäure befindet (man setzt noch   et1 {a 1/1 kg   frische Phosphorsäure zu) trägt man eine neue Menge Bariumsuperoxyd ein und man wiederholt den ganzen Prozess, wie oben beschrieben, solange, bis die erwünschte Konzentration, d. i. am besten   30%     Hots,   erhalten wird. Am Schluss der Operation sättigt man die im Wasserstoffsuperoxyd befindliche Phosphorsäure mit Bariumsuperoxyd bzw.

   Dariumhydroxyd ab, wodurch auch das gesamte, das technische   Hariumsuperoxyd   stets begleitende Eisen entfernt wird. Die weitere zum Fertigmachen notwendige Arbeit ist wie bei den bekannten Verfahren.

 a suction filter, where the barine nitrate crystals are separated from the liquid hydrogen peroxide. In this hydrogen supernatant, in which the originally added phosphoric acid is located (one still adds about 1/1 kg of fresh phosphoric acid), a new amount of barium peroxide is added and the whole process is repeated as described above until the desired one Concentration, d. i. best of 30% hots. At the end of the operation, the phosphoric acid in the hydrogen peroxide is saturated with barium peroxide.

   Darium hydroxide, which also removes all of the iron that always accompanies the technical harium superoxide. The rest of the work required to get ready is as with the known methods.
