Abstract

Quantitative analysis is carried out with the isomeric compounds, there mixtures and mixtures with other nitro derivatives. 0.1 to 0.3 g samples are applied in pyridine and polarographic recording is performed in the presence of 1) NH4Cl, NH4OH, Na2SO3 and nigrosine, 2) Na2SO3 and nigrosine, 3) NH4Cl, NH4OH, Na2SO3 and gelatin. Accuracy is ± 3%, sensitivity 10−2.

Zusammenfassung

Zur quantitativen Analyse der Isomeren DNA und DNC, des Substanzgemisches und von Mischungen mit anderen Nitroderivaten wird die Polarographie von 0,1–0,3 g-Proben in Pyridin in Gegenwart von 1. NH4Cl, NH4OH, Na2SO3 und Nigrosinlösung; 2. Na2SO3 und Nigrosinlösung und 3. NH4Cl, NH4OH, Na3SO3 und Gelatinelösung mit einer Genauigkeit von ± 3% und einer Empfindlichkeit von 10−2 durchgeführt.
