Важную роль при этом играет контроль состава этого материала для установления зависимости «содержание модификаторов — функциональные свойства». Данная работа посвящена разработке методического подхода к многоэлементному определению добавок (далее по тексту — модификаторы) Ag, Au и матричных элементов в наноматериалах на основе оксидов цинка и индия методом атомно-абсорбционной спектрометрии с электротермической атомизацией (ЭТААС) и источником непрерывного спектра. Матрицей синтезированных наноматериалов (НМ) является соответствующий оксид с возможным дефицитом кислорода из-за температурных условий синтеза (300 – 700 °C), а содержание модификаторов (Ag, Au) изменяется от 1 до 3 % масс. Найдены наиболее подходящие условия пиролиза и атомизации для последовательного многоэлементного атомно-абсорбционного анализа: температура пиролиза при определении Ag, Au (для обоих оксидов), In и Zn составляет 1000, 1600, 1200 и 900 °C соответственно; температура атомизации при определении Ag, Au (для НМ на основе оксида индия), Au (для НМ на основе оксида цинка), In и Zn — 1800, 2200, 2100, 2200 и 1500 °C соответственно. Достигнута точность определения аналитов 1 – 4 % отн. Правильность результатов подтверждена методом масс-спектрометрии с индуктивно-связанной плазмой. Разработанная методика позволяет контролировать состав синтезированных наноматериалов для их более эффективного применения в производстве химических сенсоров при обнаружении таких вредных соединений, как CO, NO2, NH3, а также в фотовольтаике.</p></abstract><trans-abstract xml:lang="en"><p>The properties of nanostructured materials based on zinc and indium oxides can be modified by adding alloying elements to obtain the necessary electrical or optical properties. For example, the specificity of the chemical properties of ZnO and In2O3 for the determination of toxic gases is achieved by immobilizing Au, Ag, etc. nanoparticles on their surface. Control of the material composition plays an important role in determining the dependence between the dopant content and functional properties of the materials. The study is aimed at the development of a methodical approach to the multi-element determination of catalytic dopants (Ag, Au) and matrix elements in nanostructured tin and indium oxides atomic using continuum source graphite furnace atomic absorption spectrometry (HR CS GFAAS). The matrix of the synthesized nanostructured materials (NM) is formed by the corresponding oxide with possible oxygen deficiency occurred due to the temperature conditions of synthesis (300 – 700°C), and the content of additives (Ag, Au) being varied from 1 to 3 % wt. Pyrolysis and atomization conditions for sequential multi-element atomic absorption analysis are determined. The most suitable pyrolysis temperatures upon HR CS GFAAS determinations of Ag and Au (for both In and Zn oxides), are 1000, 1600, 1200 and 900°C, respectively. The most suitable atomization temperatures for ETAA-NIS determinations of Ag, Au (for indium oxide based NM, Au (for zinc oxide based NM), In, and Zn are 1800, 2200, 2100, 2200, and 1500°C, respectively. The accuracy of analyte determination reached 1 – 4 % rel. The correctness of the results was proved by inductively coupled plasma mass spectrometry. The developed method provides control of the composition of synthesized nanostructured materials for their more efficient use in photovoltaics, as well as in production of chemical sensors for detection of harmful compounds like CO, NO2, NH3.</p></trans-abstract><kwd-group xml:lang="ru"><kwd>атомно-абсорбционная спектрометрия высокого разрешения</kwd><kwd>электротермическая атомизация</kwd><kwd>источник непрерывного спектра</kwd><kwd>наноматериалы</kwd><kwd>оксид цинка</kwd><kwd>оксид индия</kwd><kwd>модификаторы</kwd></kwd-group><kwd-group xml:lang="en"><kwd>high resolution atomic absorption spectrometry</kwd><kwd>electrothermal atomization</kwd><kwd>continuum source</kwd><kwd>nanomaterials</kwd><kwd>indium oxide</kwd><kwd>zinc oxide</kwd><kwd>modifiers</kwd></kwd-group></article-meta></front><back><ref-list><title>References</title><ref id="cit1"><label>1</label><citation-alternatives><mixed-citation xml:lang="ru">Sosnin D.
