Solutions containing Caro's acid and sulfuric acid can be used in the method of DE 10 80 083 which were obtained either by means of electrolysis of a sulfuric acid with a content of preferably 35% to 50% by weight, with subsequent hydrolysis of the peroxodisulfuric acid formed or by means of the reaction of 50% to 88% by weight aqueous hydrogen peroxide with concentrated or fuming sulfuric acid (oleum). In order to prepare sodium peroxymonosulfate, such H2SO5 /H2SO4 solutions are neutralized with a soda solution up to pH 2.9, freed of the precipitated Glauber salt and subsequently dried.
