Zusammenfassung
Das Verfahren beruht auf dem Aufschluß mit einem Säuregemisch (Salpeter-, Perchlor-, Flußsäure) bei normalem Druck. Ein Druckaufschluß wurde ebenfalls geprüft, war jedoch weniger geeignet. Störungen wurden durch Korrekturen berücksichtigt. Im Vergleich mit einem Standard-Referenzmaterial wurde befriedigende Übereinstimmung erzielt.
Summary
A method for the simultaneous multi-element determination of major, minor and trace elements in airborne particulates by ICP-AES was proposed based on multi-acid digestion. The methods for sample decomposition under high and ambient pressure were compared using a mixture of nitric, perchloric and hydrofluoric acids. The ambient pressure technique was finally adopted. Spectral interferences were taken into account and corrected. A recovery study was conducted for most of the elements, and a good agreement was obtained with the certified values of NBS SRM 1648 urban particulate materials using the recommended method.
