Title: distilled water reuse
Post by: galle89 on February 28, 2017, 10:23:05 AM
Hello

Ich habe build a small electrolysis to seperate silver from copper. Therefor I use distilled water, 0,1 mol/l HNO3 and a power supply. As anode = silver/copper alloy and as cathode stainless steal. The prozess works very well.

But is it possible to reuse the distilled water from the prozess?

Silver is coming reduced, copper is dissolved and maybe a little bit of zinc is dissolved. How can I remove copper and zinc from my solution, so that I can reuse the prozess water?

And whats happend when the solution is saturated? Will the prozess break down and ends?

Thanks very well

 If you wanted to reuse it in the same electrolysis just evaporate it it nearly to dryness. Condensate will contain some nitric acid hence you may use less HNO3 in the next electrolysis.

When I make the anode from a non metal pice, maybe plastics or something like that, is it possible to clean the solution from copper and zinc?

cathode is made from Iron or stainless steal. Anode plastics a similar produkt.

Almost none of this makes sense.  Please describe your procedure more fully.  It's not very likely that you have access to conductive plastics.
