“…3 In the case of selenium, there are different approaches for improving the LOD for analysis by TXRF. Compared to other preconcentration procedures used for Se in the literature, [8][9][10][11] extraction efficiency using Ag NPs is better and thus LODs.…”

“…In the last few years, different studies concerning the determination of selenium by TXRF were published. [8][9][10][11] Different sample treatments before analysis for improving the sensitivity for selenium were proposed, e.g. reduction of selenium with ascorbic acid and adsorption on the quartz reector or preconcentration of selenium by dispersive liquid-liquid microextraction (DLLME) using ammonium pyrrolidinedithiocarbamate (APDC) as a complexing agent.…”

“…Additionally, the average counts are within uncertainty the same for each solution analyses and can therefore not explain the differences in the experimental standard deviation. It was previously observed that a more complex matrix increases the background in the spectra [2,21]. Moreover, different reflectors having an altered roughness can increment the variability of the background associated with the Compton peak [13].…”

“…The same techniques plus ICP-AES were used to study K reserves in Scottish soils, 269 where it was noted that aqua regia digestion released K from phyllosilicates, excluding muscovite mica, but not from K-feldspars. Margui et al 270,271 investigated the suitability of TXRF for measurement of trace Se in soils and soil extracts. With analyte preconcentration by DLLME, a LOD of 0.05 mg kg À1 was obtained.…”

This is the 27th annual review published in Journal of Analytical Atomic Spectrometry of the application of atomic spectrometry to the chemical analysis of environmental samples. This Update refers to papers published approximately between September 2010 and August 2011 and continues the series of Atomic Spectrometry Updates (ASUs) in Environmental Analysis 1 that should be read in conjunction with other related ASU reviews in the series, namely: clinical and biological materials, foods and beverages;(2) advances in atomic spectrometry and related techniques;(3) elemental speciation;(4) X-ray fluorescence spectrometry(5) and industrial analysis: metals, chemicals and advanced materials.(6) To celebrate the 25th anniversary of JAAS, a 25-year retrospective of ASU reviews has been published(7) to highlight the development and evolution of atomic spectrometric techniques and their use in measurement applications. Specific to this review, in the field of air analysis there is ongoing interest in measuring atmospheric Hg species and evaluating procedures for the determination of the carbonaceous content of airborne particulate matter. In a measurement arena where RMs are relatively scarce, a number of useful interlaboratory comparison studies have been reported. In the field of water analysis, as in previous years, the main areas of activity are the development of preconcentration and extraction procedures and elemental speciation protocols for elements such as As, Cr and Hg. There is increasing interest in evaluating TXRF for trace analysis. In the field of soil and plant analysis, sample dissolution and extraction remain a major focus of interest-especially methods to assess bioavailability-and there is a hint that 'greener' approaches, using less concentrated acid, are becoming important. Especially notable are the continued developments in LIBS, a shift towards more widespread use of techniques such as HPLC-ICP-MS and synchrotron-based XRF, and growth in studies where multiple techniques have been applied to the same sample for trace element mapping or speciation analysis. Less desirable are the publication of variants on well-established analytical methods with marginal novelty and several instances where substantially similar articles appeared almost simultaneously in more than one journal, thus generating 'two publications for the price of one'. It is evident that MC-ICP-MS and LA-MC-ICP-MS are now so widely available in geoanalytical laboratories that applications papers, that include little of novelty from an analytical perspective, dominate the literature. However, this trend should not mask the vital research required to underpin and improve the quality of the geochemical data on which any interpretation is based. Another observation is the high proportion of analytical and applications papers with Chinese authors, reflecting the rise of atomic spectrometry in China over the past number of years.
