✦ Synopsis


A gas chromatographymass spectrometric method for determination of unsymdimethylhydrazine (UDMH) in soil and water has been developed. The method is based on derivatization of UDMH with 2-nitrobenzaldehyde, 4-nitrobenzaldehyde, 4-chlorobenzaldeyhde, 4-cyanobenzaldehyde, 4-dimethyaminobenzaldehyde, benzaldehyde and furfuraldehyde, followed by analysis of the derivative using gas chromatographymass spectrometry. The effect of ambient air and antioxidants (pyrogallol and TiCl,) to absorb dissolved oxygen from the reagents has been investigated. The method proves to be useful for UDMH analysis in soil and water, and has been used for environmental site assessment at a former missile base in Ukraine.

On a mis au point une mCthode spectromktrique de masse par chromatographie gazeuse pour la dktermination d'un-symdimCthylhydrazine (UDMH) dans la terre et I'eau. La mkthode s'appuie sur la derivation d'UDMH avec le 2nitrobenzaldehyde, 4-nitrobenzaldChyde, 4-chlorobenzaldChyde, 4-cyanobenzaldChyde, 4-dimCthyaminobenzaldChyde, benzaldkhyde et furfuraldChyde, suivie de l'analyse des derives au moyen de la spectromktrie de masse par chromatographie gazeuse. On a CtudiC l'effet de l'air ambiant et des antioxydants (pyrogallol et TiCI,) pour absorber I'oxygkne dissous des rkactifs. La methode s'avkre utile pour l'analyse d'UDMH dans l'eau et dans l'air, et elle a Ct C utilisee B des fins d'kvaluation environnementale dans une ancienne base de missiles en Ukraine.
