ok, sorry

The easiest and safest method i know of is fractional freezing. From my notes:

 

-store bought hydrogen peroxide is usually 3% H2O2, 97% H20

-water freezes at 0 degrees (obv!)

-H2O2 freezes at -11 degrees

 

depending on your freezer, if you freeze the solution, and drain it off, the drained liquid will be relatively pure H2O2.

Boiling also works

Boiling would most likely speed up the decomposition of the peroxide rather than purifying it.

Here are a few of the past discussions for you
