copper palladium nitrate

[sayf]

I have a solution of copper silver palladium nitrate
Is there a chance to separate them using caustic soda
In other words if i rise the ph of the solution to a certain value the copper hydroxide will precipitate then i filter it leaving behind silver and palladium nitrate solution then i rise the ph to a higher certain value the palladium hydroxide will precipitate leaving behind silver nitrate and so on
Can any one help me with this topic and if its practical method to separate the metals from nitrate solution
Thank you
Regards

Your suggestion will most likely get you in trouble.

I'd suggest:
1st - HCl to precipitate AgCl
2nd - Ammonum Formate reduction of Pd
2nd (alternative) - Precipitate Pd with DMG
