The effect of adding hydrogen peroxide on a methanol-based chlorine dioxide
generation process was studied. We found that the rate of chlorine dioxide
generation is increased and that chlorine, usually present as a byproduct
in the chlorine dioxide solution, can be largely eliminated when hydrogen p
eroxide is present as a coreducing agent. A possible explanation to account
for these observations was given. An implication of these experimental fin
dings for the operation of commercial chlorine dioxide generators was sugge
sted.
