Hey guys,
I done some cheap pins in AP, dissolved all the base metal and got my foils. After filtering I tested the AP with stannous and got color on the swab. Done another test in my spot plate to just confirm the purple color and it is there. Now to my question, since there is no HNO3 can I use SMB to drop any gold left in the AP solution? Or is it just collateral gold. Never run into this with AP.
Thanks,
Ken
