Microchimica Acta Aims and scope Submit manuscript

Summary

An indirect atomic absorption Spectrometric method for the determination of silicon is proposed which is based on the precipitation of an equivalent amount of lead molybdate from solutions treated with a known excess of lead ion and subsequent measurement of the lead ion remaining in solution. A typical calibration graph is linear for samples containing 0.5–7μg silicon.

Zusammenfassung

Eine indirekte Siliciumbestimmungsmethode durch Atomarabsorption wurde vorgeschlagen. Sie beruht auf der Fällung einer äquivalenten Menge Bleimolybdat aus Lösungen mit einem bekannten Überschuß von Bleiionen und nachfolgender Messung des Bleis im Filtrat. Die Eichkurve für Proben mit 0,5 bis 7μg Silicium ist linear.
