Abstract

X-ray fluorescence is well established as an analytical method for the determination of multi-element systems. It is a technique which provides high accuracy and precision. However, it has serious limitations in the lower limit of detection for elemental analysis in environmental samples. In order to overcome this limitation some method of preconcentration or enrichment of the trace elements in water samples must be provided. In recent years many techniques have been developed for this purpose. Some of these techniques involve simple chemical or physical manipulations of the sample. In all cases, the technique should be rapid, simple, and not contaminate the sample. Because it is more convenient to use solid samples for X-ray fluorescence analysis, the ideal method of preconcentration results in a solid sample.
