Dears,

I searched a lot for DMG that is used for palladium precipitation but I'm unable for find it commercially.

So is there any alternative that could be used instead of the DMG.

Thanks in advance :)
 
Thanks all for your replies :)

I tried searching the local market but I'm unable to find the commercial name for the DMG so I'm asking for an alternative.

For ebay, it'll not be cost effective and I might face some difficulties in customs as it seems that it's unknown substance here.

So is there any alternative that can do the same job as DMG ?
 
Exactly what is the job you are using it for?

If it is to refine palladium then there are alternatives. This is a short overview of how palladium metal can be refined.

Digest palladium metal in nitric acid.
Add NH4OH to pH 1-2 and filter of sediments
Add NH4OH to pH 10 and filter, removes iron and nickel
Add HCl to pH 6.5-7 and filter, removes AgCl
Add HCl to pH 3, a yellow palladium salt will precipitate
Cool the mixture and collect the precipitate in a filter, rinse with 1% HCl in DI water.
Liquids goes to the stock pot for reclamation of left over values
Reduce the diammine-palladium(II) chloride with formic acid, calcining or other method of choice

This works with concentrated solutions. You can always cement palladium from diluted solutions with zinc.
