Sodium Peroxide Extraction From Alumina Support
I've recently managed to acquire roughly half a kilogram of sodium peroxide(product picture attached). My problem, however, is that it's on some
weird alumina support which causes the solution to thicken and have a bunch of weird crap in it. I'm wondering if there are any solvents I can use to
extract the sodium peroxide from the support. I haven't been able to find any it won't react with. Any other extraction teks?

Welcome to sciencemadness
I'm not sure for pyrotechnic uses it would have to be an organic solvent that will not oxidize
If you are trying to make hydrogen peroxide from sodium peroxide
From sodium peroxide and sodium bicarbonate which should lower the pH enough to prevent decomposition and form sodium carbonate in situ upon which the
sodium carbonate adsorbs the hydrogen peroxide forming sodium percarbonate adduct.
Percarbonate
extraction of hydrogen peroxide from percarbonate using ethyl acetate which seems due to the research able to dissolve hydrogen peroxide from it's
adduct.
At this point the aluminum hydroxide will separate and is insouble in the solution.
Add water to dilute to needed concentration and evaporate the hydrogen peroxide it will be over 90%
Here is my journey into making high test Hydrogen peroxide

I was thinking something a bit along those lines, unfortunately, carbon tet is not the easiest chemical for me to get.

Oh I get it. it has the alumina to react with the sodium hydroxide that is formed to form sodium aluminate in situ and hydrogen peroxide.
Sorry about the edit the reason I thought that would be terrible is that you end up with an adduct of HCl which would react when you use it.
may also be formed from a process starting from sodium peroxide When absolute ethyl alcohol reacts with sodium peroxide at 0° C. a perhydroxide is
produced.
C2H5OH + Na2O2 -> O:NaOH + C2H5ONa.
The perhydroxide is insoluble in the mixture
Carbon dioxide converts it into sodium hydrogen percarbonate.
If you can get a soluble product the aluminum oxide should separate out.
