В ходе исследования были изучены и выбраны условия для микроволнового разложения образцов — состав кислотных смесей (HCl/HNO3) и режимы микроволнового нагрева (время и температура выдержки), обеспечивающие полное растворение исследуемых образцов. Исследованы условия АЭС-ИСП анализа феррогранатов иттрия, легированных церием, изучено влияние матричных компонентов (Y, Ce, Fe, Ga) на определение примесных элементов. В целях минимизации матричного эффекта выбраны рабочие параметры спектрометра (мощность высокочастотного генератора и скорость распылительного потока аргона), позволяющие снизить матричный эффект при определении примесей Na, Mg, Al, Si, P, K, Ca, Sc, Cr, Mn, Co, Ni, Cu, Zn, Se, Cd, Sn, Te, La, Pr, Nd, Sm, Eu, Gd, Tb, Dy, Ho, Er, Tm, Yb, Lu, Pb в феррогранатах иттрия методом АЭС-ИСП. Исследования методом АЭС-ИСП проводили в аксиальном и радиальном режиме обзора плазмы для примесных элементов, и в радиальном режиме — для матричных элементов. Пределы определения большинства аналитов находятся в интервале n · 10–5 – n · 10–4 % масс. Точность методики подтверждена методом «введено – найдено», а также анализом образцов с аттестованными содержаниями элементов. Стандартное отклонение находится в диапазоне 1 – 5 % в зависимости от выбранного режима обзора плазмы и определяемых элементов. Разработанный метод позволяет определять макро- и микрокомпоненты в феррогранатах иттрия в широком диапазоне концентраций с высокой точностью.</p></abstract><trans-abstract xml:lang="en"><p>An analytical procedure for inductively coupled plasma atomic emission (ICP-AES) analysis of iron garnets of the composition Y3 – xCexFe5 – yGayO12, where x = 0.4 – 0.5 and y = 2.4 – 2.6 with preliminary microwave decomposition of the sample is described. The compositions of acid mixtures (HCl/HNO3), as well as modes of microwave heating (holding time and temperature), providing complete dissolution of the samples are proposed. In addition to optimized sample preparation, conditions for ICP-AES analysis of cerium-doped yttrium iron garnets were studied. The effect of matrix components (Y, Ce, Fe, Ga) on the determination of doping elements was revealed and studied. The operating parameters of the spectrometer (ICP power and nebulizer flow rate) have been substantiated, which make it possible to reduce the matrix effect of Fe, Ga, Y, Ce on the elements Na, Mg, Al, Si, P, K, Ca, Sc, Cr, Mn, Co, Ni, Cu, Zn, Se, Cd, Sn, Te, La, Pr, Nd, Sm, Eu, Gd, Tb, Dy, Ho, Er, Tm, Yb, Lu, Pb in iron yttrium garnets by the ICP-AES. ICP-AES measurements were performed in the axial and radial mode for trace elements and in the radial mode for matrix elements. The limits of quantification (LOQs) of most elements ranged within n × 10–5 – n × 10–4 wt.%. The accuracy is confirmed by the spike recovery test. The relative standard deviation is in the range of 1 – 5% depending on the selected plasma view mode and the analyzed analytes. The developed method makes it possible to determine macro- and microcomponents in yttrium iron garnets in a wide range of concentrations with a high accuracy.</p></trans-abstract><kwd-group xml:lang="ru"><kwd>церий-замещенный феррогранат иттрия</kwd><kwd>атомно-эмиссионная спектрометрия с индуктивно-связанной плазмой</kwd><kwd>система микроволнового разложения</kwd><kwd>редкоземельные металлы</kwd><kwd>анализ</kwd></kwd-group><kwd-group xml:lang="en"><kwd>yttrium iron garnet</kwd><kwd>inductively coupled plasma atomic emission spectrometry</kwd><kwd>microwave decomposition</kwd><kwd>rare earth metals</kwd><kwd>analysis</kwd></kwd-group><funding-group><funding-statement xml:lang="ru">Исследование сделано за счет гранта Российского научного фонда (проект № 20-13-00180-П) с использованием оборудования ЦКП ФМИ ИОНХ РАН.</funding-statement></funding-group></article-meta></front><back><ref-list><title>References</title><ref id="cit1"><label>1</label><citation-alternatives><mixed-citation xml:lang="ru">Smirnova M.
