title: Determination of beryllium in Pt-Be alloy by atomic-absorption spectrometry after ion-exchange separation.
abstract: Traces of beryllium in platinum have been determined by graphite-furnace atomic-absorption spectrometry, the graphite furnace being coated with lanthanum or titanium carbide. The coating improves the reproducibility, sensitivity and detection limit. Platinum interferes in the beryllium determination, and an ion-exchange separation is used in the determination of beryllium in Pt-Be alloy.
