Abstract

Oppfinnelsen omhandler en fremgangsmåte for fremstilling av en alkalisk hydrogenperoksidløsning og en surgjort alkalimetallsaltløsning inneholdende klorat i en elektro-kjemisk celle som inkluderer et anodekammer (2) utstyrt med en anode (3) og et katodekammer (4) utstyrt med en oksygenreduserende katode (5). I katodekammeret blir et vandig alkalimetallhydroksid og hydrogenperoksid dannet, hvori det molare forhold MOH:H0for nettoproduksjonen derav blir opprettholdt fra omkring 0,1:1 til omkring 2:1. En fremgangsmåte for samtidig fremstilling av klordioksid er også fremlagt.
