Description

Synergetic system on the base of sulfoxides and picrolonic acid (PA) showing promise in extraction of a large number of radioactive, rare, dispersed and nonferrous metals and so inorganic and organic acids is investigated. Extraction of U, Ce, Pr, Nd, Sm, Eu, Am, Cm, Bk, Cf compounds from nitric acid solutions was investigated. It was shown that in PA - sulfoxide system strong mixed complexes with lanthanides and actinides were formed stability of which is higher by few order in comparison with data on extraction of these elements by TTA-TBP, phenylmethylbenzoylpyrazolone-TBP mixtures. It permits to separate these elements from more acid solutions with high distribution coefficients, that is important for aims of concentrating

Abstract (Russian)

Исследована синергетическая система на основе сульфоксидов и пикролоновой кислоты (ПК), перспективная для извлечения большого числа радиоактивных, редких, рассеянных и цветных металлов, а также неорганических и органических кислот. Проводилось исследование экстракции соединений U, Ce, Pr, Nd, Sm, Eu, Am, Cm, Bk, Cf из азотнокислых сред. Показано, что в системе ПК - сульфоксид с ионами лантанидов и актинидов образуются прочные смешанные комплексы, устойчивость которых при сравнении с данными по экстракции этих элементов смесями ТТА-ТБФ, фенилметилбензоилпиразолон-ТБФ на несколько порядков выше. Это позволяет извлекать данные элементы из более кислых растворов с высокими коэффициентами распределения, что является важным для целей концентрирования
