Zusammenfassung
Arbeitsbedingungen werden für die Luft-Acetylen- und die N2O-Acetylen-Flamme gegeben. Die Störungen, die in der Luft-Acetylen-Flamme auftreten, werden im einzelnen besprochen und ihre Ausschaltung durch Lanthanzusatz beschrieben. In der N2O-Acetylen-Flamme treten keine Störungen auf, wenn die Lösungen einen Ionisierungspuffer enthalten.
Summary
Recommended operating conditions for the determination of strontium by atomic absorption spectrophotometry are given for both the air-acetylene and nitrous oxide-acetylene flames. Details are given of interference effects which can occur in the air-acetylene flame and also of a method to eliminate these effects using lanthanum as a releasing agent. In the nitrous oxide-acetylene flame no interference effects occurred if all solutions measured contained an ionisation buffer.
