Abstract

Selon l'invention, du gaz de dioxyde de chlore dissous dans de l'eau est produit par le passage d'une solution de dioxyde de chlore stabilisé ou d'une solution de chlorite de sodium, avec ou sans chlorure de sodium ajouté, à travers une cellule d'électrolyse comportant une anode et une cathode. En l'absence d'une membrane semi-perméable mais en la présence d'un tampon, un anolyte comprenant un pH inférieur à 10 est produit de sorte que la dismutation du ClO¿2? ne soit pas appréciable.
