Изучение кинетики растворения природного талька проведено в проточных ячейках при 25 °C в растворах соляной, лимонной и щавелевой кислот при рН 3. Увеличение скорости растворения талька в присутствии органических лигандов цитрата и оксалата примерно в 3–4 раза характерно только для начальной стадии растворения минерала. Стационарные скорости растворения талька устанавливались примерно через 30–40 часов после начала эксперимента и составили приблизительно 3E–10–16 моль/см2с.</p></abstract><trans-abstract xml:lang="en"><p>Natural silicates are potential sources of divalent cations, which are necessary for the mineralization of CO2 in the form of carbonates. The kinetics study of the natural talc dissolution was carried out in flow-through reactors at 25 °C in the presence and absence of organic ligands — oxalate and citrate, at pH 3. Increasing of the rate of talc dissolution in the presence of citrate and oxalate, approximately 3–4 times, is typical only for the initial stage of mineral dissolution. The steady-state dissolution rates of talc were established approximately 30–40 hours after the beginning of the experiment and were equal to 3E–10–16 mol/cm2s.</p></trans-abstract><kwd-group xml:lang="ru"><kwd>карбонизация</kwd><kwd>тальк</kwd><kwd>растворение</kwd><kwd>скорость растворения</kwd><kwd>органические лиганды</kwd><kwd>цитраты</kwd><kwd>оксалаты</kwd></kwd-group><kwd-group xml:lang="en"><kwd>mineral carbonation</kwd><kwd>talc</kwd><kwd>dissolution</kwd><kwd>dissolution rate</kwd><kwd>organic ligands</kwd><kwd>citrates</kwd><kwd>oxalates</kwd></kwd-group><funding-group><funding-statement xml:lang="ru">Исследования выполнены за счет средств Российского научного фонда, проект № 22-27-00035</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">Соколова Т.А.
