Hey Picky, I would really appreciate a precise 'recipe' to make the appropriate strength for both the Cetrimide and the Ferric Nitrate solutions. I have 110 fully gold-plated telecom PCB s so will need to make at least 10 liters of solution and then re-use it several times! Many thanks and have a great 2023!
Looks like an excellent dissolving solution. Two questions please........ 1. Can I make the Cetrimide? If so what is the recipe? I have looked online and I do not see a 15% solution. 2. approximately how much iron do I need to dissolve in how much HNO3 to make the ferric nitrate solution? (to arrive at 78%) I assume I can just adjust the volumes of the components depending on the concentrations available? for example, my HNO3 is 68% so I would only add 44.2ml, and so on. Please keep these great and informative experiments coming. WELL DONE!!
Indium recovery! In modern solders, there can be indium and silver among other metals. Also some processors might contain indium. There can be quite a bit of indium in solder. Indium might become much more expensive, as it's production is only 1200t per year while silver production is around 25000t a year. There might be some indium in chemical wastes. I wonder if it is possible to recover either metallic indium or indium salts?
Thanks for sharing! You have great knowledge How many times can this solution be used before it loses the ability to dissolve tin? Do you know how to recover the tin from the solution ?
can we use a lower concentration of the citrimide solution like 5% or 10% witch is found in industrial desinfectant or can the citrimide be replaced with some other inhibitor withs is more available
Hi, can you use this solution without ferric nitrate, because is problem to make this or expensive to buy-it,,Why ferrite nitrate is needed for in the solution/ purpose of the ferric nitrate? THANKS IN ADVANCE BROTHER!
Yes you can remove it from the list. It's just used to remove the last thin layer of solder on the copper/ Solder forms alloy with copper with few micron thickness ferric nitrate removes that layer
please need help here in the uk the only product i can find with cetrimide in it is 3.0%concrete would that still work and also please also can you please do a video of you making ferric nitrate 78% please it would be a very big help
Seems like a great solution for dissolving tin I'd love to give it a try. Wondering where you can buy the cetrimide or how you can make it. Had trouble finding a answer to ether of those questions.
Try find one of these three, in pure form only 1 % would be enough for this purpose. Dodecyltrimethylammonium bromide C14: Tetradecyltrimethylammonium bromide C16: Hexadecyltrimethylammonium bromide
Thank you for this video. Can you use electrolysis to get the tin back out of solution? Or would you eventually end up dissolving some other base metals in this process?
Hi we use just dilute HCL for tin and solder removal and use heat for acclamation reaction , this way you show is new and good info but I think too much expensive is it right? And we use 3 time diluted HCL for solder and Tin removal.Did you math how much your solution? And how many times can we use?
@@PickyPlans Thanks so much for your prompt reply! I will do a trial just warming it up to say about 80C while I source the Cetrimide. Keep up your great work!
@@julianalcorso5703. Most backyard refiners, at least those without any greater chemical knowledge, will benefit from doing things the old fashioned way. Remember KISS (Keep It Super Simple). Some processes may take a little longer, but they're simple and the chemicals are cheap. A two step process, first very diluted HCL and then diluted HNO3 will do the job. Electrowinning or carbon reduction will recover the metals. Full leaching process is described in my comment (3 parts) here: th-cam.com/video/UugorCcXEYw/w-d-xo.html .
@@zero-waste Thanks for the advice! I am a winemaker and therefore have studied and understand organic chemistry but this Ewaste recovery is fairly new to me. I agree with KISS!!! All I am trying to do is remove the remaining solder from several Kg of high-grade telecom pins. as well as the remaining solder from the boards (120Kg). I tried HCL but must have had it way too concentrated (1:1) What strength would you recommend? Once again thanks so much for your help!! BTW I am in Australia, You?
@@julianalcorso5703. You really should separate fully gold plated pins from those with only partial gold plating, and process them in two batches. Tin behaves odd in many ways. One of them is: If tin solder have been in direct contact with gold plated pins a phenomenon called metal diffusion have occurred. It's best illustrated if you use a cheap soldering iron with a copper tip. The tip becomes inevitably shorter and shorter as the tin solder absorbs a tiny part of the copper tip every time you use it. Therefore, the dissolved solder from fully gold plated pins do contain gold! Metal diffusion is the reason that a two step process is needed for complete removal of solder on Printed Circuit Boards. Many backyard refiners struggle with the last remaining solder on PCBs, i.e. the components will not fall off. A small part of the solder is encapsulated in the diffusion layer of tin/copper. HCl cannot dissolve copper, but HNO3 can. Read my three part comment for tin removal process here: th-cam.com/video/UugorCcXEYw/w-d-xo.html . Try it and leave a comment if you find it can be either simplified, or improved. After tin removal the electronic components can be sorted for further processing. The bare boards are processed for Bromine extraction, and pyrolyzed yielding raw fuel oil. Finally the copper is separated out. What remains is solely glass fibers, which have so little value that it's just given away for free to a glass recycler. I process any kind of low/med./high grade Printed Circuit Boards. Currently at least 3 tons in stock, but it's way too cold for chemical processes in the winter here; awaiting summer time. During many years I've traveled to many countries visiting numerous small and large recyclers/refiners, but still haven't been in Australia; it's pretty far from Denmark, actually half the way around the globe. However, as an avid sportfisher a trip to The Great Barrier Reef for big black marlin is tempting. If I decide to go to Australia it could indeed be very nice to pass by, and enjoy a glass of delicious Australian Full Bodied red wine while discussing e-waste recycling and recovery processes.

Tin? I'm in!
Wooow It was very attractive👍🏻✌🏻
Thanks
Thanks for sharing! You have great knowledge
How many times can this solution be used before it loses the ability to dissolve tin?
Do you know how to recover the tin from the solution ?
Thanks, to about 150-200 g tin per liter.
Add HCl then filter lead chloride and percipitate tin using aluminum
can we use a lower concentration of the citrimide solution like 5% or 10% witch is found in industrial desinfectant or can the citrimide be replaced with some other inhibitor withs is more available
bonjour. attention au condensateurs dans l acide ou chaleur ,risque explosion .bonne chance

@@PickyPlans thank you so much
I’m in same boat.did you find any solution?
Ii can’t buy nitric acid here…any advice?
the best vidio❤

Why is the cetrimide orange colour?
What else is in it?
@@PickyPlans awesome. Thanks.
Really nice and fast. However, is there an alternative to the cetrimide? I simply cant find any in Europe 😕
Try find one of these three, in pure form only 1 % would be enough for this purpose.
Dodecyltrimethylammonium bromide
C14: Tetradecyltrimethylammonium bromide
C16: Hexadecyltrimethylammonium bromide
Are other ammonium quats suitable as a replacement for the cetrimide? Can you link to the source material about dissolving solder?
رائع 👍🏾👍🏾
Can you DIY make some like gel flux to make lead solder fast melting on PCB? thx before 👍🏻
Does the silver come off with solder and tin
Sir, how long can I save it after making the solution? (cEtrimide base)
About 3-4 days and up to 7 days in cold place
and then how do you make it fall?
Thank you for this video. Can you use electrolysis to get the tin back out of solution? Or would you eventually end up dissolving some other base metals in this process?
@@PickyPlans thank you. I have accepted you. You can share your video links directly to the group if you like

And we use 3 time diluted HCL for solder and Tin removal.Did you math how much your solution? And how many times can we use?
Which boards did you use to depopulate? And how many times do you actually reuse your HCL solution for the same?
can you recover the silver out from out of the solder off the boards?
If you use the HCL method, silver doesn't get dissolved in it, so it should most likely settle out to the bottom either as a fine powder or sludge
how to recovery tin from solution brother?🙏🏻🙏🏻
Adored
So sorry but I have one more question............ Would the Urea based solution have worked quicker if it were heated up or even boiled?
@@PickyPlans Thanks so much for your prompt reply! I will do a trial just warming it up to say about 80C while I source the Cetrimide. Keep up your great work!
