According to the processed final product, it is divided into the following categories: Elemental analysis is a process where a sample of some material (e.g., soil, waste or drinking water, bodily fluids, minerals, chemical compounds) is analyzed for its elemental and sometimes isotopic composition.[citation needed] Elemental analysis can be qualitative (determining what elements are present), and it can be quantitative (determining how much of each are present). Elemental analysis falls within the ambit of analytical chemistry, the set of instruments involved in deciphering the chemical nature of our world.

1. Purification method The cyanide is oxidized to CO 2 , NH 3 , N 2 by various oxidants, or the physical treatment method is used to improve the treatment effect on the basis of chemical oxidation, thereby destroying the cyanide in the cyanide-containing sewage and changing it. It is a non-toxic waste liquid. Purification of natural hair, bleaching powder, chlorine, electrolysis, Inconel SO 2 - Air Act, ozonation, biochemical oxidation and activated carbon adsorption method and the like.
2. Cyanide regeneration and recovery method According to the content, form, properties and other components of cyanide in wastewater, acidification, air stripping, desorption, zinc sulfate, ion exchange, etc. can be used to recover cyanide and copper in wastewater. , zinc and other ingredients.
3. The whole process of recycling the poor liquid to realize the technology of no cyanide-containing wastewater discharge pollution.
