The current manufacturing process for electroplating and metal surface finishing relies heavily upon the use of cyanide. Cyanide is typically employed to plate complex metals and is more tolerant to certain impurities than other substances. One of the drawbacks to using cyanide in a manufacturing capacity, however, is its extreme toxicity. Cyanide is easily absorbed by animals and humans through direct contact, vapor, or dust. For this reason, stringent regulations require that plants properly treat any contaminated water that could contain free cyanide, weak acid dissociables, and strong acid dissociables.
The chemical contamination of water is a major concern for the environmental and health authorities globally. Some anions present in the water are required for human health, but some of them are harmful. Free cyanide and nitrate are amongst the toxic agents in the aquatic environment. Cyanide is highly toxic for human beings. Industrial plants could be attributed to a major source of these toxic agents.
