the cupric chloride will be doing most of the etching (instead of requiring disposal). For now, just watch your solution turn light green. Next time you use it, the color will deepen.
Using ferric chloride to etch copper, the effect of the main variables, namely concentration, flow rate, temperature and copper content of the solution is reviewed. An optimum concentration at ca 2·25 M is noted, which is independent of temperature and flow rate....
I have PCB etching system. That had a ventilated holes above. So i thought its not good idea to keep it open permanently. So after etching is done. I remove all liquid from system and put it in plastic bottles. so that would be helpful for reusing that used ferric chloride solution. ...
1.for water treatment: sewage treatment, in order to remove heavy metal and phosphate in the water. ferric chloride liquid is an efficient and low-priced flocculant in the treatment of industrial water,industrial wastewater,city sewage and swimming pool circulating water。there is a significant effe...
Ferric chloride (FeCl3) has widespread use as an etchant in the PCB industry and for photochemical machining. Although the corrosion process of copper in FeCl3 is well known, the use of organic inhibitors of copper corrosion in FeCl3 solutions has not been reported. Such inhibition may allow mi...

seriously, this might be a far better alternative to ferric chloride and reuseable http://members.optusnet.com.au/~eseychell/PCB/etching_CuCl/index.html Mark Hammer more Awesome! Posts: 29,650 Location: Ottawa, Canada Logged Re: how do you all dispose of Ferric Chloride? #6 October ...
Hello All, I have some Ferric Chloride laying around from my previous work with PCB etching. So yesterday i came to know that Knifes can be etched too. I watched couple of video on YouTube and saw the patters on the knife and tried it on my stainless ste
