Summary

Three independent decomposition methods for organic matter are compared for use in the determination of arsenic by the hydride-AAS method. Matrix interferences in the arsine evolution cause systematic errors.

Zusammenfassung

Drei unabhängige Aufschlußmethoden zwecks Arsenbestimmung nach der Hydrid-Atomabsorptionsmethode wurden verglichen. Störungen seitens der Matrix bei der AsH3-Entwicklung sind eine der Ursachen für systematische Fehler.
