Atmosphere. In air, cyanide ions are present mainly as hydrogen cyanide (HCN). Miners, firefighters and workers of metallurgical chemical and galvanic industries are exposed largely to cyanide poisoning (Bolstad-Johnson et al. 2000).Cyanides enter into the atmosphere as a consequence of industrial processes and fires at houses and industrial halls.

Cyanide Wastewater Treatment: What You Need to Know | Sensorex

Hydrogen cyanide (HCN) is a colorless or pale-blue liquid or gas with a bitter, almond-like odor. Hydrogen cyanide interferes with the body’s use of oxygen and may cause harm to the brain, heart, blood vessels, and lungs. Exposure can be fatal. Workers may be harmed from exposure to hydrogen cyanide.

CDC | Facts About Cyanide

Cyanide is a carbon-nitrogen chemical unit which combines with many organic and inorganic compounds. The most commonly used form, hydrogen cyanide, is mainly used to make the compounds needed to make nylon and other synthetic fibers and resins.

Cyanide Blue C™ is a convenient Control Compound for Cyanide Blue™, which does not chelate cyanide and show a fluorescence intensity decrease. Cyanide Blue C™ can readily be excited from 300-400 nm, with emission centered around 460 nm in the Blue region of the visible spectrum.


The stock sodium cyanide (NaCN), zinc cyanide (ZnCN) and iron cyanide (FeCN) solutions of 1.0 g CN − /L was prepared in 1.0 L of Milli-Q water. Sodium cyanide and iron cyanide solutions were prepared by adding required quantity of NaCN and K 4 [Fe(CN) 6]·3H 2 O respectively, but zinc cyanide was prepared by adding equal volume of zinc ...

Sodium cyanide is water-reactive. Sodium cyanide decomposes on contact with acids, acid salts, water, moisture, and carbon dioxide, producing highly toxic, flammable hydrogen cyanide gas. Sodium cyanide solution in water is a strong base; it reacts violently with acid and is corrosive. Sodium cyanide is incompatible with strong oxidants.

Cyanide in Drinking-water - WHO

Cyanide enters air, water, and soil from both natural processes and industrial activities. Most cyanide in surface water will form hydrogen cyanide and evaporate. However, the amount of hydrogen cyanide formed is generally not enough to be harmful to humans. Some cyanide in water will be transformed into less harmful chemicals by microorganisms.
