Summary

Atomic absorption spectroscopy has been used to determine the copper content of commercial chlorophyllins and of the iron in Cytochrome-C. The procedure is rapid and direct as preparation involves only weighing and dissolution of the sample. The precision of the methods is excellent. The values obtained compare favorably with those obtained by the standard colorimetric methods.

Zusammenfassung

Mit Hilfe der Atomabsorption wurde der Kupfergehalt in käuflichem Chlorophyllin und der Eisengehalt in Cytochrom C bestimmt. Da zur Vorbereitung nur die Einwaage und die Auflösung der Probe nötig sind, führt das Verfahren rasch ans Ziel. Seine Genauigkeit ist ausgezeichnet und seine Resultate entsprechen den Ergebnissen der kolorimetrischen Standardmethoden.
