how can remove chloride from ferric chloride?

First i dissolved iron ore with Hcl and then i filtered it and then i  titrated that filtrate  with NaoH then i got precipitated iron ore solids by filter that solution, but more than 10% chlorides are present in that solids, so can any body tell how to remove that chlorides from that solids ?

Removing chlorides from a solution to leave only metallic copper?

I'm trying to deposit metallic copper into a piece of wood and i'm doing it with a solution of copper chloride (the alternative pcb etchant to the ferric stuff). I want to deposit metallic copper into the wood where it has soaked in and remove the chlorides altogether. Bearing in mind that i don't want much in the way of another solution, how could it be done? Could I drop in some lead to precipitate out the chloride ions or is there something else that would steal the chloride ions from copper that wouldn't be too hard for a hobbiest to obtain?

are there toxic vapours produced from using ferric chloride to etch pcb boards? Answered

Are there toxic vapours produced from using ferric chloride to etch pcb boards?  I want to present this process in a classroom but there are no windows and wondered if this would be hazardous. There's also the method of mixing hydrochloric acid and hydrogen peroxide to act as an etchant. Thanks!

Etching a pcb with bleach?? Answered

Yes i know there has been a question about this already... but im asking it again. Can you etch a pcb with bleach? I dont really want to go out and find ferric chloride or hydrochloric (muratic) acid :) I just wanted to know if this would work.  Also pros and cons would be good too, if not possible i can find a place with the right chemicals.. :) Thanks!

Can regular bleach be used as an alternative for PCB etching?

I just want to know if there are any chemicals that would be easier to get a hold of than having to go out and buy the ferric chloride or other etchants.

Use a 3d printer for etching PCBs?

Here's an idea - would it be possible to use a 3D printer to lay out the etch resist on a PCB?  It would likely only need to print a single layer.  Of course you'd need to use a material that would resist the ferric chloride but could also be removed without leaving a residue. Thoughts???

Prevent rust on a PCB? Answered

How do I prevent rust?  Or should I just not worry about the rust?  I am using single sided board etched with ferric chloride, if that matters. Also I need the copper to conduct "on the top", like if I put a multimeter on a trace it would still conduct.  So I can't use something like a clear coat spray paint. AI

What technique would be recommended for cutting through thin gauges of sheet brass and copper (Preferably cheap)?

I am currently trying to find a solution to a year and a half long problem I've been working at, and was hoping the community could help me out.  I ma trying to create miniature armatures that will always have the right proportions by etching the 'skeleton' out of thin brass (I believe it's somewhere around .02 inches thick).  I've tried toner transfer and ferric chloride etching, but I am not getting steady results with the toner transfer.  Since this isn't a circuit board, are there any other techniques I can use to cut through the metal quickly?  If it's something along the lines of a CnC machine, as long as I can make it to cut down on the costs, I'm open to the idea.  Just to give you an idea of what I'm trying now, at the moment I'm making stencils that I will spray acrylic or spray paint through onto the metal to allow for the same design every time.  Acrylic and spray paint are also resistant to ferric chloride. Thanks

Remove scratches in desk? Answered

A few years ago I got my first x-acto knife. Of course, me being 12 years old I started cutting without thinking of consequences. Now My desk is all scratched up... There are also some Ferric chloride stains on the desk and I may have spilled some superglue on it, too. My desk is made of wood and has a shiny white layer over it, picture's down there Now here is my question: Is it possible to remove the scratches? By painting it or putting a layer of x over it? If not, how can I get the scratches to be less noticable? And how do I remove superglue and Fe(III)Cl stains?

Is it possible to etch PCB's with HCL? Answered

I bought one of ladyada's USBtinyisp avr programmers a few days ago, its working great! i program alot in visual basic but i never tried anything quite like the C similar programming of the avr chips. because of that i reprogram my chip ALOT, so i decided to make a target board. i already have the "blank" board and a UV lamp to prepare it. i have sodium hydroxide to develop it. all i need is something to etch off the copper. so i was wondering: can i etch off the copper with 32% hydrochloric acid/muratic acid/HCL?

Craters on home made PCB tracks ??? How to avoid ??? Answered

Hi ... I would like to ask how do you do your own PCB - so that you have nice/solid tracks ??? I did mine by using laser printer - iron - Ferric Chloride (FeCI3). When I've finished the board ... I've took it under 30x magnifying loupe and saw a lot of craters in those copper tracks - which sometimes lead to NO CONNECTION between the copper. Or I made this = I saw a track that did transfer signal (I've checked it for continuity) but it seems to be very thin. So I've decided to put solder over it to make it solid.  But to my surprise ... as soon as I put solder over the "weak spot" ... the connection get lost. I had to make a "bridge" by using a small wire. Could you explain me, why this happened and how to make the track NICE and SOLID ??? Thank you in advance. Zholy

Do ATX Power supplies convert AC to DC power?

Hello all, I am sure this is a silly question for the experienced, but seeing as I'm just starting to really get into this stuff, any help would be appreciated. I am writing to get a bit of consensus to assure myself the a ATX power supply will convert AC power in to DC power out.  I would like to save myself the hassle of taking apart a computer if this is not the case.  In the event I'm wrong, what does convert AC to DC power? Just to give you an idea of what I need this for, this power supply will be used to run the electrolytic etching process for use with copper in a copper sulfate bath.  I'll be using the etch process to etch through copper plates (saves a lot of money compared to ferric chloride) The last question I had is if anyone knows how to discharge any residual energy within the ATX system.  I have an instructable on converting the ATX into a power supply, but I feel like I read the residual power in the system can be quite nasty if it shocks you, so I'd like to avoid that.  In fact, any suggestions would be welcomed. Thanks! Andrew
