Decomposition of hydrogen peroxide
Hydrogen peroxide in acid media is appreciably more stable than
under basic conditions. The charcoal acts catalytically and I believe
(but do not know for sure) by disproportionation to water and oxygen.
If you need to use a catalytic system platinium black works fine. Other
wise I would always use sulfite or bisulfite. Treat until no colour with
starch-iodide paper. Good luck
