Title (EN) ELECTROLYSIS CELL FOR GENERATING CHLORINE DIOXIDE
(FR) CELLULE D'ELECTROLYSE PRODUISANT DU BIOXYDE DE CHLORE
Abstract: front page image
(EN)A method for making chlorine dioxide, by passing an aqueous feed solution comprising sodium chlorite into a non-membrane electrolysis cell comprising an anode and a cathode, adjacent to the anode, while flowing electrical current between the anode and the cathode to electrolyze the aqueous feed solution and convert the halogen dioxide salt to halogen dioxide. The anode is preferably a porous anode through which the aqueous feed solution passes to maximize the conversion of chlorite to chlorine dioxide.
(FR)L'invention porte sur un procédé d'obtention de bioxyde de chlore consistant à faire passer une solution aqueuse de chlorite de sodium dans une cellule d'électrolyse non membranaire comportant une anode et une cathode jouxtant l'anode, tout en faisant circuler entre l'anode et la cathode un courant d'électrolyse de la solution aqueuse qui transforme le sel de bioxyde d'halogène en bioxyde d'halogène. L'anode est de préférence une anode poreuse que traverse la solution aqueuse pour rendre maximale la conversion de chlorite en bioxyde de chlore.
