Description

Sorption separation of plutonium and other radionuclides by fibrous complexing adsorbents from neutral and nitric acid aqueous solutions are studied. Possibility of plutonium, americium, uranium, thorium and europium separation by adsorbent POLIORGS 33 containing amidoxime and hydrazine groups from neutral salt solutions and isolation of plutonium by adsorbent POLIORGS 33A (modified by arsenazo 3) from nitric acid solutions of complex composition are established. Possibility of selective isolation of plutonium and its separation from trivalent actinides and lanthanides using POLIORGS 33A is shown

Abstract (Russian)

Изучено сорбционное извлечение плутония и других радионуклидов волокнистыми комплексообразующими сорбентами из нейтральных и азотнокислых солевых растворов. Установлена возможность извлечения плутония, америция, урана, тория и европия сорбентом ПОЛИОРГС 33, содержащим амидоксимные и гидразиновые группы, из нейтральных солевых растворов и извлечения плутония сорбентом ПОЛИОРГС 33А (модифицированным реагентом арсеназо 3) из азотнокислых растворов сложного состава. Показана возможность избирательного извлечения плутония и его отделения от трехвалентных актиноидов и лантаноидов с помощью сорбента ПОЛИОРГС 33А
