Abstract
본 발명은 이미 사용된 핵연료의 재처리과정에서 발생하는 수용액으로 부터 Nb, Sb, Ce+Pr, 악티늄족 원소들 및 주기율표 Ⅶb족과 Ⅷ족 원소들과 같은 원소를 적어도 하나 분리해내는 방법에 관한 것이다.
이 방법은 상기 수용액을 비닐피리딘 중합체 또는 공중합체를 함유한 고체수지와 접촉시키는 단계 및 상기 수용액으로부터 상기 원소 또는 원소들을 고착하는데 사용된 수지를 분리하는 단계로 구성되어 있다.
특히, 수지는 교차결합된 형태의 폴리(비닐－4－피리딘)분말이며 분리되는 원소들은 루테늄, 로듐, 팔라듐, 테크네듐, 망간, 코발트, 철, 니켈, 세륨 및 프라세오디뮴이다.
