“…6 The XPS spectra of Ag 3d from the fractured surfaces of the a Ag X O@SBA-15 original sample and b Ag X O@SBA-15 recycled sample reduction of AgO/Ag 2 O on the fresh sample to metallic Ag 0 of Ag X O@SBA-15, resulting in the loss of oxygen atoms, and the decrease in the background denominator, so the overall content of Ag element increased. Theoretically, the complete reduction of AgO and Ag 2 O to Ag would result in the increase in Ag content to 15.7% and 15.3%, respectively (Zvereva and Trunova 2012). From the above analysis, the deactivation mechanism of Ag X O@SBA-15 after regeneration can be deduced.…”

Adsorbent regeneration is critical for a continuous adsorption-regeneration process and often underestimated. In this work, the regeneration of bifunctional Ag X O@SBA-15 for [O]-induced reactive adsorptive desulfurization of liquid fuel is reported and further investigated. The spent Ag X O@SBA-15 was regenerated in various types of solvents followed by calcination and tested in multiple desulfurization-regeneration cycles. The effects of regenerate solvents were also compared systematically. The original and regenerated Ag X O@SBA-15 was characterized by X-ray diffraction, transmission electron microscopy, energy-dispersive X-ray spectroscopy, N 2 adsorption, X-ray photoelectron spectroscopy and atomic absorption spectrometry. The recovery of desulfurization capacity using various solvents follows the order of acetonitrile [ acetone [ ethanol [ methanol [ water. Owing to the complete reduction of silver species to Ag 0 and severe agglomeration of Ag 0 , the bifunctional Ag X O@SBA-15 demonstrating [ 85% (2.60 mg-S/g) of sulfur removal dramatically reduced to \ 46% (1.56 mg-S/g) after only 1st-cycle regeneration. It is suggested that polar organic species strongly adsorbed (or residual) on the spent Ag X O@SBA-15, in that case, after solvent wash may contribute to the accelerated decomposition of Ag ? to Ag 0 in the following calcination step. The desulfurization capacity decreased rather mildly in the later regeneration runs. Cautious choice of regeneration conditions and strategies to rational design stabilized adsorbents is required to avert the adsorbent deactivation.

“…Moreover, Vogt and Ralle 334 described how recent advances in XRF microscopy and the use of uorescent copper probes have started to reveal the association of Cu with neurodegenerative diseases such as Alzheimer's. In another review, 335 the main parameters of X-ray spectrometric methods (XRF, PIXE, XFM) together with AAS, ICP-AES and ICP-MS, used for the examination of the cardiovascular system, were compared, and new trends in the analysis of these samples and the main sample preparation approaches were considered. Dillon 336 presented recent advances in and applications of three prominent synchrotron radiation techniques, m-XRF spectroscopy/imaging, XAS, and m-IR spectroscopy, and highlighted how these tools were useful to the medicinal chemist.…”

“…Особый интерес представляет взаимодействие эссенциальных и неэссенциальных элементов, токсических микроэлементов. Известно, что токсические эффекты кадмия, ртути и свинца могут быть нейтрализованы эссенциальными элементами, такими как селен и цинк [3]. Рекомендованными микроэлементами для диагностических целей в крови являются Cu, Zn, Mn, Ni, Se, Pb, Cr, As, Cd, Tl и V [4].…”

Introduction: Determination of essential and toxic elements in human blood is an important and urgent task within monitoring, environmental and hygienic studies accomplished in evidence-based medicine when population health risks are assessed. Aim: Biomonitoring of unexposed adult population in the Russian Federation. Methods: The contents of V, Cr, Mn, Ni, Cu, Zn, As, Se, Sr, Cd, Tl and Pb were determined in the blood of adults (n=80, aged 40-45 years) living in rural areas in the Western Urals region of the Russian Federation. The measurements were carried out using Agilent 7500cx quadrupole inductively coupled plasma mass spectrometer (Agilent Technologies, USA) with an octopole reaction-collision cell (ORS) in conformity with the Methodical Guidelines 4.1.3230-14 and 4.1.3161-14 (FR. 1.31.2014.17064) developed by the authors. Results: The arithmetic mean (AM) content of elements in blood of this group amounted to 0.13 g/l (V); 4.75 g/l (Cr); 13.41 g/l (Mn); 4.06 g/l (Ni); 827.15 g/l (Cu); 5369.36 g/l (Zn); 0.42 g/l (As); 123.10 g/l (Se); 22.75 g/l (Sr); 0.45 g/l (Cd); 0.04 g/l (Tl); 14.37 g/l (Pb). The validity of the results was confirmed by analyzing standard samples of SERONORMTM Whole Blood L1 and SERONORMTM Whole Blood L2 (Norway). The results are presented as basic statistical indicators: minimum and maximum values, arithmetic mean (AM), 5th, 50th, 95th percentiles and are interpreted in accordance with up-to-date international requirements. Conclusions: We compared the range of P5-P95 values for unexposed groups of adults in the Western Urals and the Far North region with the results produced by several hygienic studies conducted in Germany, Italy, France and Canada. As a result, we established elevated concentrations of chromium, manganese, and nickel in the blood of adults from Russia. The contents of copper, zinc, selenium, and arsenic in the blood of adults living in the Russian Federation were different from the reference values used in such diagnostic laboratories as ALS Scandinavia, SIVR LIST Italy and in the monograph by Norbert Titz (USA).
