platinum question

[myfalconry76]

Sorry guys but I'm a little confused on this. From what I understand if I read it right. Platnium solution should be red! Is this correct? I've done a stannous test and there is platinum in the solution, but it's emerald green! Dose it change cholor as it evaps. Or did I miss something? Just to throw this in. I got it under control with the safety stuff. I like life
Thank ya thank ya thank ya

Easily the colored washed out by copper or nickel...

 

[Geo]

Agreed. Copper or nickel or any other metal that is green in solution. I would say, from experience, dilute what you have by half with water and cement the values on copper. Agitate the solution frequently or add a bubbler just for the agitation. It does help oxidize the copper. After a day passes, remove the solution from the container and move the black powder to another container and add clean water. Add the solution back to the container and replace the copper. Any amount left may takes several days to completely cement out. You will have the most of the PM's after the first day.Once all of the PM's are out of solution, rinse them well with water. Once the copper(II) chloride Is dilute enough, it turns into milky green/white copper(I) chloride and it mixes with the black powder. Let it settle and decant the solution into a clean container. Be careful not to pour out any solids. Add to the solids a solution of water 90% and HCl 32° baume 10%. This will dissolve the copper(I) chloride but not the PGM powders. Repeat the water and dilute HCl rinses a few times until the solution stays color free. End with a water rinse. If you dissolve these powders, you will have your red solution. A word of warning, Platinum and by acquaintance, all other PGM's, are toxic when in an ionic state or when it is in solution. Pt is the primary component in chemotherapy treatments for cancer. The Pt kills the cancer at one rate of speed and it kills the person at a slower rate of speed. In theory, The cancer should die first. Platinum chloride is toxic to all living things.

To repeat Geos warning wear proper gloves, lab wear and avoid splashes when working with PGM solutions keep your work area clean and wash it down well if you do spill some solution, no one is sure how much exposure you need to become ill from them so keep the risk as low as possible.

While PM stannous test will end in black, after initial red/orange, copper or nickel will not

From what I've been reading about toxicity of pgms. It doesn't say anything about iminate death. There are a few health issues that can arise from exposer but even those are treatable. And studies on people that work with or around pgms for long periods of time are inconclusive. Not saying I'm not going to do my best to prevent health and safety problems. If proper safety is adhered to I shouldn't have any issue.even with minute exposer. Yet I will still do my best to mitigate that.

I doubt I will change your mind, since you've discounted much of the advice you've been given in the past, so I won't waste my time trying.

For the benefit of anyone else who reads this thread in the future, Geo and Nick have given valid warnings about the dangers of platinum salts. Do NOT be comforted by myfalconry's statements. Platinum salts are very dangerous, and once one develops sensitivity to them, it is NOT treatable.

Wel... He does have in his signature "on the word of no one, or, take nobodys word for it"

Guess he wants to find out for himself like todd

 

[nickvc]

To repeat my warning, Geo's and Dave's.
Look up platinosis causes and effects and read it very carefully and fully digest what it says.
The problem is it's caused by small amounts of salts which never leave the body, like mercury poisoning it's progressive, your fine one day next your ill and stay ill or worse.

 

[4metals]

To discount or otherwise minimize the severity of platinosis is a disservice to others who may be reading this. It affects those who ignore its existence as those who are well aware of it's potential equally.

Members who have been here long enough remember a very wise and valuable member here known as Freechemist, a PHd chemist who worked for a major refiner in Europe and succumbed to idiopathic fibrosis of the lung. Here was a man who had forgotten more than I have ever known about Platinum group metals, yet sadly he was a victim of platinosis.

Do not underestimate the risk.

what the check are you talking about??? I haven't discounted any advice anyone has given me. I was simply stating what I have read. Don't blame for what the data states and other sources. I am talking precautions to be safe and healthy as everyone should. If I'm wrong and your so concerned with it maybe you should write some of the authors of theses documents and express your concerns to them. Even someone in this thread stated no one really knows how much is to much. I do promote safety and your concerns as I like my crappy life. But to jump down my throat and totally disregard the context of my post in such away other than adding clarity, well that's just being a bully. To further this note, I would also like to add I enjoy this forum and it's contents. I find it informative. But when some one makes a comment about littiture they have read and the information it contains. If it is wrong you can set your ego aside and give viable reasons instead of degrading the person who post it add clearity.

Even though this post dose not go into detail about said topic. I find it a much better response. Way smoother. Thank and I will not underestimate the potential harm. Thank you!!!

 

[Topher_osAUrus]

Can you post up some links to these articles/documents you speak of?

All i can find is information outlining the dangers of pgm salts on the human body.

[Topher_osAUrus]

I didnt see anything in there about it being safe... Or that there is treatment/cures for sensitivity or poisoning.
That was a msds that read like a horror story. Not really anything i would want to take lightly.

Id rather be safe than sorry.

Hopefully im not the only one.

 

[4metals]

If this was football our behavior here would amount to piling on! The falcon man has acknowledged the potential of exposure and all continued postings can only lead to provocation, so let's all play nice and move on.

Thanks for providing the link. I still think your birds are cool, and a natural solution to my groundhog issues!

I didn't say it was safe, precautions should be taken. Over exposer is bad. And like I said I value my life. That's why I have modified my fume hood with a hinged plexi glass front. With holes and arm length gloves bonded to those holes, kinda like a incubator for babies where you can stick your arms in the gloves. But I must say I did this to protect myself from toxic fumes from the beginning.

Groundhogs, you would need a large furugenious hawk or a golden eagle. That's not to say that a large female red tailed hawk couldn't take one. But Groundhogs are very strong from digging and would put on one hell of a fight and have very strong jaws and large incisers to boot.
I highly recommend falconry to anyone who loves birds of prey and hunting.

 

[4metals]

Well those groundhogs certainly get plenty of exercise digging up my garden. And a week doesn't go by that I don't see a Bald Eagle fly over my pond but apparently they have no interest either. Must be a lot more tender easy takings around than bothering with a muscular old groundhog.

At least my .22 still works!

Ah, that sounds pretty safe... And interesting to say the least.

Please forgive my misinterpretation of your post. Im sorry for the misunderstanding.

That does sound like a very good fume hood though. Id love to see some pictures. Whenever i see something thats done in a very creative and clever way, it gets the ol' juices goin' upstairs, then those gears start cranking...eventually spawning ideas (after the smoke clears)
