Abstract

En vandig lesning av klorsyre og alka-limetallklorat fremstilles i en elektroly-tisk celle (4) som har et anodekammer (10), et katodekammer (30) og minst ett ionebytte-kammer (20) mellom anodekammeret (10) og katodekammeret (30). Fremgangsmåten omfatter tilførsel av en vandig løsning av et alkali-metallklorat til ionebyttekammeret (20) , elektrolyse av en anolytt (12) i anodekammeret (10) for å generere hydrogenioner, foring av hydrogenionene fra anodekammeret (10) gjennom en kationbyttemembran (16) og inn i ionebyttekammeret (20) for å erstatte alkalimetallioner og for å fremstille en vandig IrEning av klorsyre og alkalimetall-klorat, samt foring av alkalimetallioner fra ionebyttekammeret (20) inn i katodekammeret (30) .
