I did some research about removing iron along with copper from saturated AP solution with electrolysis and it is indeed possible, in fact it we can remove all the main contaminant metals including nickel, zinc, cobalt, tin, lead etc. leaving the HCl relatively clean for reuse. By tuning the cell it's even possible to plate them out selectively but for our purposes I think all together will be fine. I will do a small experiment tomorrow and make a post about it.
