palladium sulfide

[bastinado]

If i have palladium sulfide

how i would get pure palladium metal , when nitric acid is not available ?

 

[Lino1406]

Roast in air, then melt

Thanks Lino

But for your information

two years ago i asked about this thing andyou answerd me the same answer

please consider the following

-I cant do roasting at home (i can just put the sulfide under flame)
-Nitric acid is not available legally

is there is any chemical process to remove sulfur from palladium sulfide ?

 

[Lino1406]

H2O2 is converting it to PdO and SO2, even SO4=

I utilized H2o2 50% concentration

i found it make huge amount of vapor and boiling within few seconds

am not shure of some of palladium sulfide turned to PdO or not but no clear change in color

Check liquid for SO4=
