Determination of cyanide ion by homogeneous catalysis and gas chromatography
A simple procedure for the determination of trace levels of cyanide ions is described and evaluated. The procedure is based on the cyanide-catalyzed cleavage of benzil in the presence of methanol to produce benzaldehyde and methyl benzoate. The concentrations of these products are determined by gas...

| Zusammenfassung: | A simple procedure for the determination of trace levels of cyanide ions is described and evaluated. The procedure is based on the cyanide-catalyzed cleavage of benzil in the presence of methanol to produce benzaldehyde and methyl benzoate. The concentrations of these products are determined by gas chromatography. Linearity between gas chromatographic response and cyanide concentration is observed from 0.05 to 3 ppm cyanide; a detection limit of 1 ppb is calculated. A series of anions is shown not to interfere. |
