MULTIELEMENT DETERMINATION IN SEDIMENTS, PORE WATER AND RIVER WATER OF UPPER AUSTRIAN RIVERS BY TOTAL-REFLECTION X-RAY FLUORESCENCE

摘要

Multielement determination in sediments, pore water and river water has been carried out using total-reflection X-ray fluorescence (TXRF), electrothermal atomic absorption spectrometry (ETAAS) and hydride generation atomic absorption spectrometry (Hyd-AAS). TXRF in particular facilitates multielement determination by allowing easy quantification with internal one-element standardization, and is therefore central to these investigations. In connection with the simplicity of sample preparation an attractive analytical procedure for routine analyses has been worked out. It allows a quick and accurate multielement determination on the < 40 mu m fraction of river sediment and on pore water and river water. (C) 1997 Elsevier Science B.V. [References: 7]
