Determination of 15N/14N and 13C/12C in Solid and Aqueous Cyanides

“…3 Because cyanide is highly toxic, its degradation both in natural waters and in industrial process solutions has been and continues to be the subject of intensive study. 4,5 The purpose of this report is to present an analytical method that allows stable isotope techniques to be applied to the study of cyanide degradation. The method permits analysis of 15 N/ 14 N and 13 C/ 12 C in solid cyanide salts and in free cyanide (CNaq + HCN aq ) contained in simple aqueous solutions.…”

“…The chemistry of cyanide is quite complex due to the fact that it can form a wide variety of compounds and complexes . Because cyanide is highly toxic, its degradation both in natural waters and in industrial process solutions has been and continues to be the subject of intensive study. , …”
