ABSTRACT
This chapter briefly discusses the application, chemical properties and physical properties of cyanogen. It presents detailed information on the air analysis of cyanogen. Cyanogen is used as a fuel gas, fumigant, and propellant. It is a colorless gas with almond-like odor, highly soluble in water, alcohol and ether, highly toxic and highly flammable. During the air analysis of cyanogen, air is drawn through a 0.8 mm cellulose ester membrane to separate cyanogen from particulate cyanide. Cyanide ion is analyzed by cyanide ion-selective electrode. Cyanogen in the air may also be analyzed by OSHA Method PV2104, a partially evaluated stopgap method. Cyanogen reacts with the coated reagent to form a derivative. Samples are then desorbed with toluene and analyzed by gas chromatography (GC) using nitrogen-phosphorus detector (NPD).
