Description

The metals Cr, Cu, Fe and Ni are determined and calibrated in pure B2O3 with atomic absorption spectroscopy. B2O3 is dissolved in low-concentrated hydrochloric acid and the metals are analyzed directly. The detection limits are found to be in the range of 0.005 to 0.01 μg/ml of these metals. The measurements showed a systematic signal depression of the absorbance values. The influence of different B2O3 concentrations is discussed. (orig.)

Abstract (German)

Die Metalle Chrom, Kupfer, Eisen und Nickel werden in reinem Boroxid mittels Atomabsorptionsspektroskopie erfasst und kalibriert. Dazu wird B2O3 in verduennter Salzsaeure geloest und die Metalle direkt analysiert. Die Nachweisgrenzen liegen zwischen 0,005 und 0,01 μg/ml fuer diese Metalle. Bei den Messungen wurde eine systematische Signaldepression der Extinktionswerte festgestellt. Die Beeinflussung durch verschiedene B2O3-Konzentrationen wird diskutiert. (orig.)
