Microchimica Acta Aims and scope Submit manuscript

Summary

A procedure is described for the determination of carbon by closed flask combustion. It involves electrical ignition of the sample (15–20 mg) wrapped in a high melting glass fiber, absorption of the CO2 in NaOH-BaCl2 solution, separation and dissolution of the BaCO3 formed in HCl and back titration with NaOH. This method has been tested with organic compounds containing nitrogen, sulfur and chlorine.

Zusammenfassung

Ein Verfahren zur Kohlenstoffbestimmung mit Hilfe der Kolbenverbrennung wurde beschrieben. 15 bis 20 mg der in hochschmelzender Glasfaser verpackten Probe werden elektrisch gezündet, das Kohlendioxid in einer Natronlauge-Bariumchloridlösung absorbiert, das Bariumcarbonat abgetrennt, in Salzsäure gelöst und mit Natronlauge zurücktitriert. Das Verfahren wurde mit organischen Verbindungen überprüft, die Stickstoff, Schwefel bzw. Chlor enthielten.
