摘要

The extensive use of cyanide in everyday industrial operations requires close monitoring with reliable methodologies and instrumentation. Mention cyanide and you almost always get an over-reaction due to its highly poisonous nature. And rightly so, the cyanide complex (CN-) binds with the enzyme cytochrome C oxidase to inhibit cellular respiration and energy production, resulting in cytotoxic hypoxia that very rapidly affects the central nervous system and heart. In simpler terms, it's an effective poison for most living organisms. Yet, it's also a very useful compound in today's economies. More than 1 billion kg of cyanide compounds are produced annually in the U.S. alone for a variety of industrial and manufacturing process applications. These include its use in pesticides and fumigants, plastics, electroplating, dyes, textiles, specially chemicals and pharmaceuticals, petroleum refining, steel production, microelectronics manufacturing, and (mostly) mining. Cyanide is a primary material used in gold mining operations, to leach the gold metal out of low-gold content ores. In mining, as well as in other process situations, there is a significant potential for having the cyanide compounds as process wastes get into the local water supplies. And, of course, the added possibility of the intentional contamination of drinking water and food products with cyanide is a potential Homeland Security threat.
