Adam, very thanks, you cleared my doubts on this.
Still, there is 2 other questions that I looking for any comment.
Is ammonium persulfate reusable? like sodium persulfate or cupric
chloride.
Is possible to copper electroplate pcb boards in a sodium persulfate
bath?? Using copper anodes and when the bath is copper saturated.
This last question is strange, but is why i wish to have it this bath,
if could be possible a 2 in 1.
