      <abstract xml:lang="ru">
        <p>Изучена экстракция церия (3+) трибутилфосфатом. По зависимостям коэффициента распределения от концентрации высаливателя и экстрагента вычислены константы экстракции. По их значениям соли церия располагаются в ряд хлорид&amp;lt; сульфат &amp;lt; нитрат, отвечающий понижению «жесткости» анионов по Пирсону.</p>

        <p>Extraction of cerium (3+) with tributyl phosphate was studied. The extraction constants were calculated from the dependences of the distribution coefficient on the concentration of salvent and extractant. According to their values, cerium salts are arranged in the series chloride &amp;lt; sulfate &amp;lt; nitrate corresponding to the Pearson reduction of the "hardness" of anions.</p>
