Tungsten/Tunsten trioxide solubility

Dissolution of Tungsten by Hydrogen Peroxide

I doubt that concentrated H202 will be anymore easy to acquire.

I have done this before with 30% hydrogen peroxide. There are a couple of small issues if you go this route.

A soluble peroxytungstate ion can form. More details are available here: http://www.sciencemadness.org/talk/viewthread.php?tid=6862

Has anyone tried fenton reagent for dissolving the tungsten? Even with my 120vol H2O2 it's sooooo slow.
