| 摘要 |
The invention relates to a process for purifying hydrogen peroxide in aqueous solution, in accordance with which such a solution is first of all caused to pass through a strongly cationic resin mass in the acid form, it is then cooled to a temperature between 0 DEG C and the freezing point of the solution and caused to pass through an anionic resin mass of average strength in the basic form, the said mass being cooled so that the temperature of the solution before and during passing through the anionic resin remains constant and, finally, the said solution is caused to pass through an adsorbing resin and, if appropriate, filtered. |
