|Title:||Evaluation of preconcentration methods for the determination of trace amounts of rare earth elements by x-ray fluorescence analysis using a conventional x-ray tube system and a synchrotron radiation source|
|Author:||De Vito, I|
|Abstract:||Trace amounts of rare earth elements (REE) were preconcentrated by chemofiltration methods using the organic reagents o-(3,6-disulfo-2-hydroxy-1-naphthylazo)benzenearsonic acid (Thorin) and 2,2 '-(1,8-dihydroxy-3,6-disulfonaphthylene-2,7-bisazo)bisbenzenearsonic acid (Arsenazo III) as complexing agents for the REE. The resulting specimens (thin film) were then analyzed by an x-ray fluorescence method using two different instruments: a conventional x-ray tube system and a synchrotron radiation source. The results from these two systems were compared with respect to radiation damage, accuracy, detection limits and ease of analysis. Copyright (C) 2001 John Wiley & Sons, Ltd.|
