Обоснован состав реакционной смеси для перевода пробы в раствор и оптимизированы параметры микроволнового нагрева. Правильность определения элементов с помощью разработанной методики подтверждена методами варьирования навески и «введено – найдено». Результаты определения сопоставлены с полученными безэталонным методом рентгенфлуоресцентного анализа. Методика характеризуется хорошей воспроизводимостью и позволяет существенно сократить время анализа по сравнению со стандартными методиками.</p><sec><title> </title><p> </p></sec><sec><title> </title><p> </p></sec></abstract><trans-abstract xml:lang="en"><p>A method for AES-ISP determination of Ti, V, Cr, Fe, Co, Ni, Cu, Zn, and Ta in recycled cemented tungsten carbide is developed including preliminary microwave sample decomposition in a steam pressure vessel (autoclave). We have specified composition of the reaction mixture for sample dissolution and optimized the parameters of microwave heating in the autoclave. Correctness of the results is proved by the method of sample weight variation and spike tests. The results of analysis are compared with the data obtained by standardless method of x-ray fluorescence spectrometry. The technique is characterized by good reproducibility and allows significant reduction of the analysis time due to combination of the multi-element method of AES-ISP and microwave sample preparation.</p></trans-abstract><kwd-group xml:lang="ru"><kwd>вторичное вольфрамсодержащее сырье</kwd><kwd>металлокерамические твердые сплавы</kwd><kwd>микроволновая пробоподготовка</kwd><kwd>АЭС ИСП</kwd></kwd-group><kwd-group xml:lang="en"><kwd>secondary tungsten-containing raw</kwd><kwd>recycle cemented tungsten carbides</kwd><kwd>cemented tungsten carbide</kwd><kwd>microwave sample preparation</kwd><kwd>AES-ISP</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">Панов В.
