Zusammenfassung

Die Proben werden mit HNO3/H2SO4/V2O5 oder HNO3/HClO4 aufgeschlossen; Se wird elektrolytisch auf einem Platindraht niedergeschlagen und durch AAS mit gleichzeitiger elektrothermischer und Flammen-Atomisierung bestimmt. Ergebnisse werden mitgeteilt für die Analyse von Standardreferenzmaterialien („Bovine Liver“ und „Albacore Tuna“, 1−3±0,2 ppm Se).

Summary

For the determination of selenium in biological materials the samples are digested with an HNO3/H2SO4/ V2O5 or an HNO3/HClO4 mixture. Selenium is then electrolyzed onto a platinum wire, followed by atomic absorption spectrometry with simultaneous electrothermal and flame atomization. Results for the reference materials Bovine Liver and Albacore Tuna are reported (1−3±0.2 ppm Se).
