Seperating h2o2 methods
Hey all
I'm very much a beginner and don't know how to go about this. I'm trying to disolve some metals for a side project and it calls for an acid and
hydrogen peroxide as an oxidiser. It seems in Australia h2o2 is very hard to get and the only cheap source I could find was is a hair dressers bleach
cream.
I've used it and it does the job but I'm left with the cream as well and the contents that I actually want.
Is there a way to distill/leach/seperate the h2o2. I know I can't hear it due to its volatility but I think I read somewhere that alcohol/methanol
will disolve it and the alochol can then be vacuum distilled off?
Any thoughts
Thanks

Easiest source of H2O2 in aus is hydroponics suppliers.
Failing that go straight for a chemical supplier.
Third option is to buy 6% from the pharmacy and con entrate by boiling down or freezing. Both methods are written about on this board.

Never found that as a source but yes oxy plus is 50% (more than enough for what im doing) at a cost of 85$ per 5 liters.
Sure beats my 12% for $12 per liter with the added cream id have to deal with.
