Cyanide Analyzer Matthias G. Monn Overview

The Cyanide Analyzer Matthias G. Monn can perform continuous analysis of heavy metals, Cyanide (CN-), and many other parameters in water. Technologies employed are colorimetric (photometric) and ion-selective electrodes (ISE). Low consumption of reagents and very high reagent stability ensures person-free operation, direct measurements, standard addition, and titration support the ideal measurement strategy. The robust design and high-quality parts of the Cyanide Analyzer guarantee a long lifetime and minimum maintenance efforts. Automated calibration and cleaning steps support this goal.

Sources
Any chemical compound containing the cyano- group -C=N with the carbon atom triple-bonded to the nitrogen atom is a cyanide. The cyano-group can be found in various kinds of gaseous, liquid and solid compounds. Cyanide is introduced into organic molecules by displacement of the corresponding organic halide during industrial processes. Typical fields of business encountering cyanide are the steel industry, gold and silver mining, production of tints and varnish, synthetic resins, synthetic fibres, electroplating, coal and crude oil production.

Toxicology
For cyanide the guideline value for chemicals that are of health significance in drinking water according to World Health Organization (WHO) is 0.07 mg/liter as total cyanogenic compounds. Similar to hydrocyanic acid, cyanides are extremely toxic as a consequence of being able, even with very weak acids (e.g. water), to protonate and build hydrogen cyanide (HCN).

Method
Cyanide is measured as chelate complex between CN- ions in the water and sensitive spectrophotometric reagent dye. Change of the intensity of the visible light throughout cuvette containing formed complex is directly proportional to Cyanide concentration.
