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.
