Re: Help Me!! I havew to refine palladium !

Ok i got that , we have to avoid oxidations in argon or hydrogen atmosphere. But what do you think that is the right temperature .
Will under melting point work .?

Re: Help Me!! I havew to refine palladium !

Thanks to you we now know all the procedures . except turning dimethylglyoxime palladium complex into metallic palladium .
We try melting with induction but we failed we try with oxygen torch still a fail .
what do you think that we have to do to get into metal .
Thanks for all responses .

Re: Help Me!! I havew to refine palladium !

i saw one video that i have to put it in oven to heat till it becomes black and than melt can you confirm if that fine

Re: Help Me!! I havew to refine palladium !

Just to keep you informed we separete the aqua regia but we failed in electrolysis so we take the other part and added (Dimethylglyoxime C4H8N2O2 )because we cant find your acid and then after 24 hours we have this solution separated

Re: Help Me!! I havew to refine palladium !

want to be sure: so we need to dissolve in aqua regina than use electrolysis to get Pd for that we need carbon cathodes . And what type of anodes?

Re: Help Me!! I havew to refine palladium !

thanks for your help .
I want to ask you something is there any possible way to make NaBH4 or Na2S2O4 because as the component itself I cant find anywhere to buy in my country .

Re: Help Me!! I havew to refine palladium !

i talk to the chimist he said that we used as you told aqua regia and the structure of the solution is not black that was a misunderstanding the colour of the solution was yellow to red (like orange ). sorry for confusing !

Re: Help Me!! I havew to refine palladium !

Hi sir this is all that happend .
After we disband the material(20%Pd/c) into nitric acid we filter it using filtring paper than we added Dimethylglyoxime(photoNr.1) to precipitate(drop,separete) it .
Because this kind of component(photoNr.1) is not more founded what can we use instad of that.

Re: Help Me!! I havew to refine palladium !

after filtering tha carbon i get dirty solution do you know what element do i need to recover(drop)Pd from dirty sulution . please if i am not clear i will explan better .

Help Me!! I havew to refine palladium !

Hi all . I have a substance mixture of : palladium(Pd)20% on carbon = 20%Pd/c and want to know how to refine it.
the element that i have is 20%Pd/c .
