Description

Extraction of technetium(VII) and americium(III) by tetrasubstituted by lower edge calix[4]arenes containing carbonyl and ester groups in the cone conformation was studied for choosing extractants for fractionation of liquid radioactive waste produced as a results of nuclear fuel reprocessing. It was established that both types of extractants are selective and highly effective agents for technetium(VII) extraction both from acid and alkaline solutions. Under the conditions studied no extraction of americium(III) takes place

Abstract (Russian)

С целью выбора экстрагентов для фракционирования жидких радиоактивных отходов переработки ядерного топлива изучена экстракция технеция(VII) и америция(III) тетразамещенными по нижнему ободу каликс[4]аренами, содержащими карбонильные и сложноэфирные группы, в конформации конус. Установлено, что оба типа экстрагентов являются селективными высокоэффективными для извлечения технеция(VII) как из кислых, так и щелочных растворов. В изученных условиях экстракция америция(III) не происходит
