Сорбент синтезирован впервые в Институте органического синтеза УрО РАН с использованием «золь-гель»-технологии. Сорбцию палладия (II) проводили в условиях конкурентного процесса в присутствии 9 возможных сопутствующих ионов металлов. В интервале pH от 1,0 до 4,0 палладий (II) в статических условиях количественно и селективно извлекается на ДТОАП из раствора, содержащего ионы переходных металлов, в том числе, платины (IV). Для полного извлечения палладия (II) в фазу сорбента необходимо 30 мин. Показано, что сорбция палладия (II) имеет обратимый характер, количественная десорбция иона металла с поверхности сорбента возможна с применением 1 %-го раствора тиомочевины в1 Мсоляной кислоте. При сорбции в динамических условиях достигнуто отделение палладия (II) от платины (IV) и сопутствующих ионов неблагородных металлов. Установлено, что ДТОАП количественно извлекает до 0,2 ммоль/г палладия (II). Разработана методика атомно-абсорбционного определения палладия (II) с предварительным концентрированием на модифицированном полисилоксане, которая апробирована при анализе модельных и промышленных растворов с высоким солевым фоном.</p></abstract><trans-abstract xml:lang="en"><p>Polysiloxane modified with groups of rubeanic acid (dithiooxamidated polysiloxane (DTOAP)) is proposed for extraction of palladium (II) from the solution against the background of the accompanying components. Sorbent was synthesized for the first time at the Institute of Organic Synthesis (Ural Branch of the Russian Academy of Sciences) using «sol-gel» technique. Sorption of palladium (II) was carried out under competitive conditions with 9 possible accompanying metals ions present. Palladium (II) is quantitatively and selectively recovered under static conditions with DTOAP from a solution containing transition metal ions, including platinum (IV). It takes 30 minutes for complete extraction of palladium (II). Reversible character of palladium (II) sorption is shown. Quantitative desorption of metal ion from the sorbent surface is possible using a 1% solution of thiourea in 1 M hydrochloric acid. Sorption under dynamic conditions provides separation of palladium (II) from platinum (IV) and concomitant ions of base metals. DTOAP provides quantitative extraction of palladium (II) in an amount up to 0.2 mmol/g. The developed method of the atomic-absorption determination of palladium (II) with a preliminary concentration on a modified polysiloxane was tested in analysis of model and industrial solutions with a high saline background.</p></trans-abstract><kwd-group xml:lang="ru"><kwd>сорбция</kwd><kwd>палладий</kwd><kwd>полисилоксан</kwd><kwd>дитиооксамид</kwd><kwd>золь-гель</kwd><kwd>атомно-абсорбционная спектрометрия</kwd></kwd-group><kwd-group xml:lang="en"><kwd>sorption</kwd><kwd>palladium</kwd><kwd>polysiloxan</kwd><kwd>dithiooxamide</kwd><kwd>sol-gel</kwd><kwd>atomic absorption spectrometry</kwd></kwd-group><funding-group><funding-statement xml:lang="ru">РФФИ № 16-33-00292 мол_а.</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">Дробот Д.
