Removing chlorides from a solution to leave only metallic copper? Answered
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?
