Исследованы сорбционные и комплексообразующие свойства модифицированного сорбента по отношению к торию (IV) и определены основные количественные характеристики сорбции ионов металла. Построена изотерма сорбции тория синтезированным сорбентом и найдены оптимальные условия концентрирования (pH = 4; V = 20 мл; mсорб = 0,05 г). Рассчитанное значение сорбционной емкости (CTh = 8 · 10–3 моль/л) составило 853 мг/г. Изучено влияние разных минеральных кислот (HClO4, H2SO4, HNO3, HCl) на десорбцию тория (IV) в статических и динамических условиях: в качестве десорбента предпочтительно использовать 2 М HNO3. Изучено влияние мешающих ионов и скорости подачи раствора пробы и элюента на извлечение тория в динамических условиях. Степень извлечения ионов тория (IV) при оптимальных условиях превышает 92 %. Разработана методика сорбционно-фотометрического определения тория (IV) в морской воде.</p></abstract><trans-abstract xml:lang="en"><p>A chelating sorbent based on a copolymer of maleic anhydride with styrene containing fragments of p-aminobenzoic acid is synthesized. The sorption and complexing properties of the modified sorbent relative to thorium (IV) are studied and the main quantitative characteristics of metal ion sorption are determined. An isotherm of thorium sorption with the synthesized sorbent is constructed and optimal concentration conditions (pH = 4; V = 20 ml; msorb = 0.05 g) are specified. Calculate value of the sorption capacity is 853 mg/g (CTh = 8 Ч 10–3 mol/liter). The effect of various mineral acids (HClO4, H2SO4, HNO3, HCl) on desorption of thorium (IV) in static and dynamic conditions is studied. The maximum desorption of thorium (IV) occurs in nitric acid. The degree of extraction of thorium (IV) ions under optimal conditions exceeds 92%. A technique of sorption-photometric determination of thorium (IV) in seawater is developed. </p></trans-abstract><kwd-group xml:lang="ru"><kwd>сорбент</kwd><kwd>сорбция</kwd><kwd>торий</kwd><kwd>концентрирование</kwd><kwd>десорбция</kwd><kwd>спектрофотометрия</kwd></kwd-group><kwd-group xml:lang="en"><kwd>sorbent</kwd><kwd>sorption</kwd><kwd>thorium</kwd><kwd>concentration</kwd><kwd>desorption</kwd><kwd>spectrophotometry</kwd></kwd-group><funding-group><funding-statement xml:lang="ru">Фонд Развития науки при Президенте Азербайджанской Республики — Грант № EIF-KETPL-2-2015-1(25)-56/19/4.</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">Ye F., Tang Y.
