Reclaiming Copper from Sodium Persulfate #2: Stainless Steel Anode
I got my hands on some pieces of stainless steel to replace the graphite anode.
Reader’s Digest version: the mess got bigger. Green is the new blue.
What I’ve learned:
- Stainless steel doesn’t seem to work well, the solution quickly turns green.
- The green color could be Iron(II)-Sulfate, though that is not yet verified. Anyway it’s not really a success.
