Summary
The N-oxides of pyridine and of its homologs and cyano, nitro and halogenated derivatives have been studied by differential pulse polarography. The sensitivity is approximately 0.5μg/ml. Thus analysis of these compounds at theμmol level based on the N-oxide function is feasible.
Zusammenfassung
Die N-Oxide des Pyridins, seiner Homologen und deren Cyan-, Nitro- und Halogenderivate wurden mit Hilfe der differentiellen Puls-Polarographie untersucht. Die Empfindlichkeit des Verfahrens beträgt etwa 0,5μg/ml. Somit ist die Analyse dieser Substanzen in der Größenordnung ihrer Mikromole auf der Grundlage ihrer N-Oxidfunktion durchführbar.
