[0002] In industrial production processes such as electroplating, circuit board manufacturing, and metal surface treatment, nitric acid is often used to etch and clean copper workpieces. During this process, copper reacts chemically with nitric acid and enters the solution, generating copper-containing nitric acid waste liquid. Copper-containing nitric acid is a nitric acid solution containing copper ions and is a hazardous chemical with strong oxidizing and corrosive properties. To treat copper-containing nitric acid waste liquid, it is often necessary to add reagents to the waste liquid. The chemical reagents react with the copper-containing nitric acid waste liquid to achieve the treatment purpose.
