Removal of Trace H202 from Sulfuric Acid
I made some sulfuric acid using the sulfur dioxide/oxidiser method using concentrated hyrogen peroxide and am planning on using in a synthesis where
leftover peroxide would not be ideal (peroxides and organics, you know, the friendly combination). I am fairly certain all of it will react but I cant
be certain. What catalysts could I use to decompose any remaining peroxide quickly that wouldn't react with the acid?

Formaldehyde/formic acid?
Edit: maybe just any organics? Trace H2O2 in H2SO4 is just like a very weak piranha soln.

Maybe just heating the acid to its boiling point is enough? At high temperatures H2O2 isn't stable and as a plus you will also make the acid water
free (98%).

Just heat it up you crazy bastards, H2SO5 decomposes at elevated temperature.
100*C is more than adequate and i suspect you will want to boil it down to remove water anyway.
Sufficiently advanced science is indistinguishable from madness.

Easiest and fastest way, it's not even needed to BOIL sulphuric acid, so less risk
