摘要：

A procedure was developed for the determination of 1,1-dimethylhydrazine by reversed-phase high-performance liquid chromatography with spectrophotometric detection and preliminary derivatization by the reaction with 4-nitrobenzaldehyde. Conditions were selected for the chromatographic separation and the detection of the peaks of the reagent and 4-nitrobenzaldehyde dimethylhydrazone. The optimum conditions were found for the derivatization of 1, 1-dimethylhydrazine with 4-nitrobenzaldehyde. The determination limit of 1,1-dimethylhydrazine in aqueous solutions was 120 mug/L (2 muM/L).
