Die Probe wird mit Salzs\u00e4ure, Wasserstoffperoxid und Salpeters\u00e4ure aufgeschlossen. In verd\u00fcnnter Salzs\u00e4ure wird die Absorption von Eisen mittels einer Luft-Acetylen-Flamme bei einer Wellenl\u00e4nge von 248,3 nm mit einem Atomabsorptionsspektrometer gemessen.<\/p>\n
Diese Methode eignet sich zur Bestimmung von Eisen in Zinklegierungen.<\/p>\n
