Триметиларсин получали методом фотохимической генерации с использованием реактора оригинальной конструкции. Обоснована целесообразность введения активированного угля в процессе обработки графитовой печи вольфрамом для получения наночастиц карбида, которые повышают эффективность сорбции. Оптимизированы режимы фотохимической генерации и отгонки триметиларсина, а также температурные условия концентрирования и атомизации мышьяка. Разработанная аналитическая методика применена для определения As в водопроводной воде. Абсолютный и концентрационный пределы обнаружения мышьяка, вычисленные по 3s-критерию, составили 0,38 нг и 31 нг/л соответственно.</p></abstract><trans-abstract xml:lang="en"><p>The properties of permanent sorbent-modifiers (iridium, zirconium and tungsten carbides) are investigated with regard to trapping gaseous trimethylarsine and subsequent electrothermal atomic absorption determination of arsenic. Trimethylarsine is produced by photochemical vapor generation using an original reactor. Introduction of the activated carbon upon graphite furnace treatment with tungsten appeared expedience for production of carbide nanoparticles which enhance sorption efficiency. The parameters of photochemical vapor generation of trimethylarsine and thermal conditions of its trapping and atomization are optimized. The developed analytical scheme is applied for As determination in tap water. The absolute and concentration limits of As detection (calculated by 3s-criterion) are 0.38 ng and 31 ng/liter, respectively.</p></trans-abstract><kwd-group xml:lang="ru"><kwd>electrothermal atomic absorption spectrometry</kwd><kwd>trapping</kwd><kwd>permanent modifiers</kwd><kwd>photochemical vapor generation</kwd><kwd>arsenic</kwd><kwd>электротермическая атомно-абсорбционная спектрометрия</kwd><kwd>концентрирование</kwd><kwd>перманентные модификаторы</kwd><kwd>фотохимическая генерация паров</kwd><kwd>мышьяк</kwd><kwd>триметиларсин</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">Sturgeon R.
