На основе экспериментальных данных определены формы сорбирующихся ионов твердой фазой анионита. В слое Штерна–Гельмгольца проходит сорбция пентагидроксоалюминат- и пентагидроксогаллат-ионов. Рассчитаны значения кажущихся констант и энергий Гиббса ионообменных равновесий. Полученные значения полной обменной емкости галлат-ионов 55–58 г/кг в статических условиях обуславливают использование анионообменной смолы АН-31 в процессе концентрирования ионов галлия из щелочных алюминатных растворов.</p></abstract><trans-abstract xml:lang="en"><p>The paper studies sorption of aluminum and gallium in the form of hydroxocomplexes on the AN-31 weak-basic anion-exchange resin at a temperature of 298 K from standardized test solutions. On the basis of experimental data the paper determines forms of ions sorbed by the solid phase of the anion-exchange resin. Sorption of pentahydroxoaluminate and pentahydroxogallate ions occurs in the Stern-Helmholtz layer. The paper calculates values of apparent constants and Gibbs energies of ion-exchange equilibrium. The obtained values for the full exchange capacity of gallate ions equal to 55–58 g/kg under static conditions cause the use of the AN-31 anion-exchange resin in the concentration of gallium ions from alkaline aluminate solutions.</p></trans-abstract><kwd-group xml:lang="ru"><kwd>глиноземное производство</kwd><kwd>щелочные алюминатные растворы</kwd><kwd>галлат-ионы</kwd><kwd>алюминат-ионы</kwd><kwd>слабоосновные аниониты</kwd><kwd>сорбция</kwd><kwd>формы сорбирующихся ионов</kwd></kwd-group><kwd-group xml:lang="en"><kwd>alumina production</kwd><kwd>alkaline aluminate solutions</kwd><kwd>gallate ions</kwd><kwd>aluminate ions</kwd><kwd>weak-basic anion-exchange resins</kwd><kwd>sorption</kwd><kwd>forms of sorbed ions</kwd></kwd-group><funding-group><funding-statement xml:lang="ru">Министерство образования и науки Российской Федерации (государственный контракт № 14.577.21.0127 от 20.10.2014 г.)</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">Hassanien M.M., Kenawy I.M., El-Menshawy A.M., El-Asmy A.A.
