Microchimica Acta Aims and scope Submit manuscript

Summary

A specific colorimetric method is described for the determination of nitroanthraquinones. It is dependent on the red color produced on treatment of the sample with tetraethylene pentamine or imino bis-propylamine. The color is stable and is not affected by the presence of water in the system.

Zusammenfassung

Eine spezifische kolorimetrische Methode zur Bestimmung von Nitro-anthrachinonen wurde beschrieben. Sie beruht auf der bei Behandlung der Probe mit Tetraäthylenpentamin oder mit Iminobispropylamin auftretenden Rotfärbung. Diese ist beständig und wird von anwesendem Wasser nicht beeinflußt.

Résumé

On décrit une méthode colorimétrique spécifique pour doser les nitro-anthraquinones. Elle met en jeu la couleur rouge produite en traitant l'échantillon par la tétra-èthylénepentamine ou par l'imino bis-propylamine. La coloration est stable et n'est pas affectée par la présence d'eau dans le système.
