Dissolving Platinum Group Metals with HCl and H2O2 - VIDEO

In this video:

I use HCl and 12% H2O2 to dissolve mixed black powder PGMs

I precipitate the platinum out of the solution with saturated ammonium chloride

Then I make clean chlorine gas using trichloroisocyanuric acid (swimming pool chlorine tablets) and hydrochloric acid in a gas generator

I bubble the chlorine into my the palladium solution to form an ammonia soluble brick-red palladium salt

The palladium salt is dissolved in 10% ammonia and solids filtered out

Then hydrochloric acid is added to re-acidify the ammonia and the beautiful bright canary yellow pure palladium salt precipitates out

The salt is transferred to a fused quartz dish and calcined into pure palladium sponge

Here is the video of the entire process:
