Beschreibung
Zusammenfassung:	The invention relates to a method for producing an ultrapure, aqueous, long-term- and storage-stable, and thus transportable chlorine dioxide solution, comprising the steps of providing chlorite, providing peroxodisulfate, and combining chlorite and peroxodisulfate in an aqueous system and in a molar ratio of peroxodisulfate to chlorite [S2O82−]/[ClO2−] of greater than 1, forming the aqueous chlorine dioxide solution, wherein no additional buffer is added to produce the aqueous chlorine dioxide solution. The invention further relates to a corresponding chlorine dioxide solution, to the use of said chlorine dioxide solution, and to a device for producing the chlorine dioxide solution.
