Title
(EN) METHOD FOR OXIDISING SULFATE
(FR) PROCÉDÉ D'OXYDATION DE SULFATE
Abstract
(EN)
The present invention provides a method for oxidising sulfate, with the method comprising the steps of oxidising sulfate (SO42-) at a working electrode; and providing an ultrasonic field at the working electrode. Also provided is an apparatus for oxidising sulfate, with the apparatus having a working electrode in a reaction space; an electrolyte comprising persulfate (S2O82-) and/or sulfate (SO42-) in the reaction space; and an ultrasonicator for providing an ultrasonic field at the working electrode.
(FR)
La présente invention concerne un procédé d'oxydation de sulfate, le procédé comprenant les étapes consistant à oxyder du sulfate (SO4 2-) au niveau d'une électrode de travail; et à générer un champ ultrasonore au niveau de l'électrode de travail. L'invention concerne également un appareil d'oxydation de sulfate, l'appareil comportant une électrode de travail dans un espace de réaction; un électrolyte comprend du persulfate (S2O8 2-) et/ou du sulfate (SO4 2-) dans l'espace de réaction; et un dispositif à ultrasons sert à générer un champ ultrasonore au niveau de l'électrode de travail.
