There are various types of etchant in use:
Ferric Chloride, HCL acid and hydrogen Peroxide
Dilute Nitric Acid.
Which is the best way to dispose of these chemicals. Given that we don't all reside in countries that offer chemical waste disposal facilities?
I have access to Nitric acid as it's commonly found in Chemical Labs in Universities and High school labs locally and is imported in Bulk. It's simpler to handle than mixing the HCL and H2o2. Ferric Chloride is hard to come by.
