Microchimica Acta Aims and scope Submit manuscript

Summary

A method has been proposed for the rapid determination of copper and antimony in lead alloy used for telephonic cable sheath. The sample is dissolved in a nitric acid solution and the determination is made by atomic absorption spectrophotometry. The calibration is simply effected with aqueous standard solutions, since no difference was detected between this calibration and the standard addition method.

Zusammenfassung

Ein Verfahren zur raschen Bestimmung von Kupfer und Antimon in der für Telefonkabelumhüllungen verwendeten Bleilegierung wurde angegeben. Die Probe wird in Salpetersäure gelöst und die Bestimmung durch tomabsorptions-Spektrometrie durchgeführt. Die Eichung erfolgt mit wäßrigen Standardlösungen, zumal gegenüber der Standardzusatzmethode keine Differenzen auftreten.
