“…All these materials can be studied at either the bulk scale or the microscopic scale, depending on the type of sample and information needed. For example, trace elements in coal fly ash particles have been investigated by TXRF [148] as suspensions to determine total concentration (e.g. to assess potentialities for recycling or disposal) or as single particles (e.g.…”

Trace elements analysis is a fundamental challenge in environmental sciences. Scientists measure trace elements in environmental media in order to assess the quality and safety of ecosystems and to quantify the burden of anthropogenic pollution. Among the available analytical techniques, X-ray based methods are particularly powerful, as they can quantify trace elements in situ. Chemical extraction is not required, as is the case for many other analytical techniques. In the last few years, the potential for X-ray techniques to be applied in the environmental sciences has dramatically increased due to developments in laboratory instruments and synchrotron radiation facilities with improved sensitivity and spatial resolution. In this report, we summarize the principles of the X-ray based analytical techniques most frequently employed to study trace elements in environmental samples. We report on the most recent developments in laboratory and synchrotron techniques, as well as advances in instrumentation, with a special attention on X-ray sources, detectors, and optics. Lastly, we inform readers on recent applications of X-ray based analysis to different environmental matrices, such as soil, sediments, waters, wastes, living organisms, geological samples, and atmospheric particulate, and we report examples of sample preparation.

“…The TXRF technique was used by Detcheva et al 322 to study the colouration of medieval glass bracelets found in the necropolis of Stambolovo and the castle of Mezek in Bulgaria. However, Zhao et al 321 studied 46 stratied glass eye beads in the Hubei Provincial Museum, Wuhan, China using portable XRF and Raman spectrometers.…”

“…The beads originated from the Warring States Period (about 433 BC) and were reported to be typical soda-lime-silicate glasses with a low content of K 2 O and MgO and two types of colorants: antimonybased opaciers/colorants and oxidised transition metals such as Co, Cu and Fe. The TXRF technique was used by Detcheva et al 322 to study the colouration of medieval glass bracelets found in the necropolis of Stambolovo and the castle of Mezek in Bulgaria. The authors provided a description of their technique, which involved analysing samples as slurries in a detergent (Triton X114) and reported that colouration of the samples was caused by Co, Fe and Mn.…”

This review collects the research of the recent years on biological or environmental studies in which Total Reflection X-Ray Fluorescence Spectrometry (TXRF) was used as a chemical analytical technique for quantification of elemental content. Although it is not a novel technique, its application in biological and environmental samples has extended in the last years.TXRF is a useful analytical technique used for simultaneous qualitative and quantitative determination of a wide range of chemical elements, from sodium until uranium, including halogens with low matrix interferences. The major advantages of this technique include the small amount of sample required and the relative simplicity of sample preparation. Direct analysis of samples is also possible, shortening preparation time, reducing reactive consumption, and simplifying the whole analysis process. Furthermore, the low detection limit makes TXRF an excellent technique for the determination of ultra-trace, trace and major elements (concentrations range from ppb to percent) in environmental and biological samples.
