Why is heating not an option, do you not have a hotplate? The easiest way would be to dry it back to iodine probably.
You can also decompose the H2O2 into water and oxygen. Manganese dioxide would work but then you would have MnO2 contamination. This could be
removed by filtering however.
Silver should also work to decompose the H2O2 if manganese dioxide is not available. This might take longer, but will not leave contamination.

KI will make short work of H2O2 as well, didn't think of that, good idea. And no problem!

How about adding CaSO3 to it ?
CaSO4 shall be formed in reaction with H2O2 and CaSO3. It can too be filtered off.
But BaSO3 shall be better, if you have access to it.
