Abstract

L'invenzione concerne un procedimento per la purificazione di perossido di idrogeno da anioni. Secondo il procedimento, una soluzione acquosa almeno al 20% p/p di perossido di idrogeno viene fatta passare a contatto di una resina anionica media in forma basica ed a matrice stirene divinilbenzene, la temperatura tra 0°C e la temperatura di congelamento della soluzione, preferibilmente ad una temperatura inferiore a -8°C, durante il suo trattamento con la resina.
