The total reflection X-ray fluorescence technique (TXRF) was used for the routine analysis of city waste incineration ash. Subjects of these analyses were digested ashes (a) and aqueous leaching solutions (b). The accuracy of TXRF was estimated in comparison with atomic absorption spectroscopy (AAS) and atomic emission spectroscopy (ICP-AES) measurements. Satisfactory agreement was found between the results of the different methods for both types of samples. In addition to the direct measurements without prior sample preparation sample type (b) was used to compare three different extraction methods. In each case a dithiocarbamate derivative was used as complexing agent. The separation of the precipitate was performed with a silicagel column, by liquid/liquid extraction and by leaching the sample on a quartz target. Satisfying agreement was found between direct measurements and the different extraction methods. [ABSTRACT FROM AUTHOR] |
