Gas chromatography - mass spectrometric determination of unsymdimethylhydrazine in soil and water by derivatization with aromatic aldehydes

A gas chromatography — mass 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...

Description
Summary:A gas chromatography — mass 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 chromatography — mass spectrometry. The effect of ambient air and antioxidants (pyrogallol and TiCl3) 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 méthode spectrométrique de masse par chromatographie gazeuse pour la détermination d'unsymdiméthylhydrazine (UDMH) dans la terre et l'eau. La méthode s'appuie sur la dérivation d'UDMH avec le 2‐nitrobenzaldehyde, 4‐nitrobenzaldéhyde, 4‐chlorobenzaldéhyde, 4‐cyanobenzaldéhyde, 4‐diméthyaminobenzaldéhyde, benzaldéhyde et furfuraldéhyde, suivie de l'analyse des dérivés au moyen de la spectrométrie de masse par chromatographie gazeuse. On a étudié l'effet de l'air ambiant et des antioxydants (pyrogallol et TiCl3) pour absorber l'oxygène dissous des réactifs. La méthode s'avère utile pour l'analyse d'UDMH dans l'eau et dans l'air, et elle a été utilisée à des fins d'évaluation environnementale dans une ancienne base de missiles en Ukraine.
