Hi everyone,
I am new to the Forum and I need your help.
I have some potassium hexachlororodate K3RhCl6 that I no longer use and would like to separate pure rhodium from it.
How can I do?
Please note that I work in a fairly well equipped chemical lab and am used to handling chemicals and using general lab equipments.
Thank you very much for your attention.

Re: K3RhCl6
You can try electrolysis or reduction with strong reducer, like SnCl2 or v
Ascorbic acid.

Thank you ChenBeier.
I had also thought electrolysis but I have no idea about the right process conditions (e.g. type of electrodes, electric potential, concentration)...

Re: K3RhCl6
I would react the salt first with sulfuric acid, to get rid of the Chloride.
The remaining Rhodiumsulfate can be electrolysed. Cathode what ever you like. Anode carbon preferred.
