Recent developments in cyanide detection: a review Ma J; Dasgupta PKAnal Chim Acta 2010[Jul]; 673 (2): 117-25The extreme toxicity of cyanide and environmental concerns from its continued industrial use continue to generate interest in facile and sensitive methods for cyanide detection. In recent years, there is also additional recognition of HCN toxicity from smoke inhalation and potential use of cyanide as a weapon of terrorism. This review summarizes the literature since 2005 on cyanide measurement in different matrices ranging from drinking water and wastewater, to cigarette smoke and exhaled breath to biological fluids like blood, urine and saliva. The dramatic increase in the number of publications on cyanide measurement is indicative of the great interest in this field not only from analytical chemists, but also researchers from diverse environmental, medical, forensic and clinical arena. The recent methods cover both established and emerging analytical disciplines and include naked eye visual detection, spectrophotometry/colorimetry, capillary electrophoresis with optical absorbance detection, fluorometry, chemiluminescence, near-infrared cavity ring down spectroscopy, atomic absorption spectrometry, electrochemical methods (potentiometry/amperometry/ion chromatography-pulsed amperometry), mass spectrometry (selected ion flow tube mass spectrometry, electrospray ionization mass spectrometry, gas chromatography-mass spectrometry), gas chromatography (nitrogen phosphorus detector, electron capture detector) and quartz crystal mass monitors.|Chromatography, Gas/methods[MESH]|Colorimetry/methods[MESH]|Coordination Complexes/chemistry[MESH]|Cyanides/*analysis[MESH]|Electrophoresis, Capillary/methods[MESH]|Gas Chromatography-Mass Spectrometry/methods[MESH]|Luminescent Measurements/methods[MESH]|Spectrophotometry, Atomic/methods[MESH]|Water Pollutants, Chemical/*analysis[MESH] |
