HI3855 CTK Cyanide

Cyanide refers to all of the CN groups in cyanide-compounds that can be determined as the cyanide ion CN^—. In most natural waters the molecular HCN form predominates. In solutions of metal cyanides, the CN group may also be present as a complex of varying stability. Cyanides are extensively used for extraction of silver/gold ores, metal-cleaning and electroplating baths, coke ovens and other chemical processes. There are mainly two chemical treatments to remove cyanides from waste-waters: one is chlorination and the other is the alkaline method.

Cyanides react with the pyridine-pyrazolone reagent to form a blue complex in neutral buffered solution. The absorbance of this colored product is proportional to the concentration of cyanide present in the aqueous sample.
