Recovering Platinum-Group Metals in Catalytic Converters

[@aidavewaste2576]

what did you put the glass beaker in.was it water or ammonium water.please and thanks

[@yakupyazici7971]

hello please help me. ammonium chloride, a yellow precipitate formed. Is that palladium powder? Why is the solution still red when palladium is separated? Does ammonium chloride precipitate metals other than palladium?

Hello friend, do you think it would be possible to do this work with áqua régia?

[@chemistry7119]

Yes! You need denox all nitric acid and ad fresh hydrochloric acid. Evoporting aqua regia to sirup and ad hcl to not see brown fumes.

[@royalrefining6182]

Did you dissolve the platinum salt in water?

hello, does nitric acid harm pgms precipitation? thanks 

[@chemistry7119]

Yes! Need evaporating using concentrated HCL to eliminated nitric acid.

[@dirceudepin7755]

@@chemistry7119 ok,thank you

[@dirceudepin7755]

hello, I ask if you can answer me what is the proportion of hcl and bleach and what percentage should I use bleach, example: 12% or 6%?  Feedback translate

Muy bien.

Thankyou sir

Nice job! Just a little advice, you should use gloves, platinosis is serious medical condition caused by platinum salts. Even a drop of chloroplatinic acid on your skin can cause it. Health has no price. Cheers!

[@chemistry7119]

Hi! Yes it very poson shit. :-) It also use to manufacture anti cancer drugs. Very old and poverful stuff. :-)

[@knowldedge5012]

even a drop? I wanted to do some tests but I am worried now that even such a tiny exposure can cause it.

[@johnsheppard1476]

@@knowldedge5012 not really!You'll need a lot of exposure to get any symptoms!I generally didn't care about such stuff and got it on my hands countless times over the years of dealing with PGMs and never had any issues!Unless you deliberately put a hand in some highly saturated solution you won't really have any platinosys!

[@knowldedge5012]

@@johnsheppard1476 these guys on the forums are really saying that even brief exposures could cause that, it would make sense that you need repeated exposures over time but this is not something to play with, I wonder how this really works
