Die Bestimmung von Schwermetallspuren in organischen Waschrohstoffen mit Hilfe der Atomabsorptions-Spektralphotometrie (AAS)

Determination of Heavy Metal Traces in Organic Raw Materials for Washing Agents Using Atomic Absorption Spectrophotometry (AAS) In the past years AAS has been widely employed for the determination of traces of metals in the ppm range. After a short historic account, the author explains the principle of the method and describes a fusion process applicable to organic raw materials for washing agents. The actual determination of the elements Fe, Cu, Cr, Ni and Mn are referred to. Finally, the author deals with the sensitivity of the method, its reproducibility and accuracy.
