“…The application of the proposed analysis technique made it possible to determine the composition of semiconductor materials with a standard deviation of s r = 0.10. Using this approach to analyze the composition of nanocrystalline SnO 2 with Au and Sb additives, it was possible to establish that gold was immobilized on the SnO 2 surface, while antimony was distributed between the surface and the volume of the SnO 2 grains [202]. A similar approach using the partial and complete dissolution of nanocomposites and the subsequent analysis of the obtained solutions by the ICP MS method was employed to determine the concentration of chromium with s r = 0.07 and to study its distribution between the volume and the surface of SnO 2 nanocrystals [90].…”

Tin dioxide has huge potential and is widely studied and used in different fields, including as a sensitive material in semiconductor gas sensors. The specificity of the chemical activity of tin dioxide in its interaction with the gas phase is achieved via the immobilization of various modifiers on the SnO2 surface. The type of additive, its concentration, and the distribution between the surface and the volume of SnO2 crystallites have a significant effect on semiconductor gas sensor characteristics, namely sensitivity and selectivity. This review discusses the recent approaches to analyzing the composition of SnO2-based nanocomposites (the gross quantitative elemental composition, phase composition, surface composition, electronic state of additives, and mutual distribution of the components) and systematizes experimental data obtained using a set of analytical methods for studying the concentration of additives on the surface and in the volume of SnO2 nanocrystals. The benefits and drawbacks of new approaches to the high-accuracy analysis of SnO2-based nanocomposites by ICP MS and TXRF methods are discussed.

“…Trace level determinations of gold are usually performed by using atomic absorption spectrometry (AAS) [2], inductively coupled plasma atomic emission spectrometry (ICP-OES) [3] and inductively coupled plasma mass spectrometry (ICP-MS) [4]. However, in many cases the presence of a complex sample matrix precludes obtaining reliable results by direct application of those spectrometric techniques.…”

A gold(III)-imprinted thiocyanato-functionalized silica network of type SBA-15 was prepared by co-condensation of tetraethoxysilane (TEOS) with thiocyanatopropyltriethoxysilane (TCTES) in the presence of Pluronic123 and Au(III) ions. Compared to the non-imprinted material, the imprint has a higher selectivity and adsorption capacity for Au(III). The maximum static adsorption capacity for Au(III) is 475 mg·g−1 for the ion-imprinted, and 62 mg·g−1 for the non-imprinted sorbent. The imprint was applied to the sorption of Au(III) from digested geological samples prior to its determination by graphite furnace atomic absorption spectrometry. Adsorption is fast and does not substantially prolong the analytical procedure. Under optimum conditions, the detection limit for Au(III) is 2 ng·g−1. The method was validated by analyzing certified reference materials, and results were in good agreement with certified values. The procedure was successfully applied to the separation and determination of gold in complex geological samples. Graphical abstractSchematic presentation of the preparation of ion-imprinted thiocyanato-functionalized mesoporous silica and its application for the preconcentration of gold from digested soils before its determination by slurry sampling graphite furnace atomic absorption spectrometry (GF AAS).

“…This work is aimed at developing an approach to detecting gold in novel semiconductor nanomaterials based on tin dioxide via TRXF without preliminary decomposition of samples. Since no standard samples for novel materials are available, we have developed the method and grounded the results of detection of gold in analyzed samples based on tin dioxide using inductively coupled plasma mass spectroscopy (ICP MS) after decomposition [10].…”

A novel approach to detecting gold in tin dioxide advanced nanomaterials via total reflection X ray fluorescence analysis (TRXF) is proposed. Data of gold and tin detection acquired via the nonstandard method for powders and with the use of an internal standard technique in aqueous suspensions are compared. Accuracy of the gold detection in powder nanomaterials via TRXF without sample decomposition is shown.
