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 det
