      <abstract xml:lang="ru">
        <p>2-этилгексиловая ортофосфорная кислота (D2EHPA) и 2,4,4-триметилпентановая ортофосфорная кислота (Cyanex272, компания «Cytec», США) использовались для извлечения марганца из растворов серной кислоты, содержащих Co, Mg, Ca и Na. Было выяснено, что Cyanex272 обладает чуть большей способностью к выделению марганца, чем D2EHPA. Кроме того, было обнаружено, что увеличение температуры приводит к ухудшению селективности марганца.</p>

        <p>Di(2-ethylhexyl) phosphoric acid (D2EHPA) and bis(2,4,4-trimethylpentyl) phosphinic acid (Cyanex272 manufactured by Cytec, USA) were used to extract manganese from sulfuric acid solutions containing Co, Mg, Ca and Na. Cyanex272 was found to have slightly higher selectivity towards manganese than D2EHPA. In addition, it was found that an increase in temperature had a negative effect on the selectivity for Mn.</p>
