We use ammonaical silver staining of our gels, which uses 8g silver
nitrate per liter of basic (ammonia and NaOH) solution. We generate
liters of this waste, and we were wondering if anyone successfully
reclaims the silver. I've checked with several waste metal reclaimation
companies that handle photographic waste, but they tell me that it's not
worth their (or my) while to recover the silver. Can anyone point me in
the direction of a company that'll handle this sort of reclaimation? Or
can anyone tell me that I'm wasting my time?
Thanks for your help.
