Gas-chromatographic determination of 1,1-dimethylhydrazine in water
2006
A gas-chromatographic procedure for the determination of 1,1-dimethylhydrazine in water was developed on the basis of its reaction with 4-nitrobenzaldehyde yielding the corresponding hydrazone, the extraction of the latter from water with an organic solvent, its subsequent preconcentration by evaporation, and the determination on a gas chromatograph with a nitrogen-phosphorus detector. The determination limit of 1,1-dimethylhydrazine is 0.03 μg/L. The relative error of the determination is no larger than 22% in the concentration range 0.06–0.60 μg/L and 33% at a level of 0.03 μg/L.
