โœฆ Synopsis

A simple method for the determination of tract amounts of CN' and/or SCN' in water is suggested. The method is based on the prior transformation of CN' or SCN' into BrCN by treating the sample with bromine; the water sample is then analyzed by gas-solid chromatography and the BrCN is selectively detected by an electron capture detector.

Cyanides and/or thiocyanates at concentrations as low as 0.01 p.p.m. can be detected.

A method has been developed for the-direct determination of alkyl amine hydrochlorides in aqueous solution, The method involves conversion of the hydrochloride salts to the free amines in the injection port of a gas chromatograph, followed by chromatographic separation and detection of the free amin
