Purifying aqueous hydrogen peroxide solutions on ion-exchanging resins |
摘要 |
The invention relates to a method of purifying an aqueous hydrogen peroxide solution by passing the solution over a cationic resin. The invention consists in passing it over the cationic resin under conditions in which the hydrogen peroxide solution is maintained at a temperature of between its freezing point and +10° C., advantageously between 0° C. and +5° C., so as to limit contamination of the solution by sulphate ions. |
