Abstract

Thorium extraction and possible separation from monazite leaching solution was studied. Primary amine Primene JM-T was select ed for t horium ext ract ion processing. Various experiment s were t est ed and est ablished for t he t horium liquid -liquid extraction process. The screening of extractant, lower pH conditions, extractant variation and extraction isotherms construction, and finally, stripping studies were established.

본 연구는 모나자이트 침출액으로부터 용매추출을 통한 토륨의 추출 및 분리 가능성에 대해 연구하였다. 토륨 용매추출 공정을 위해 1차 아민계 추출제인 Primene-JM-T가 선택되었다. 토륨의 액-액 추출 공정을 위해 다양한 조건의 실험이 수행되고 조건이 확립되었다. 연구 결과로부터 추출제 검증, pH 조건, 추출제의 변화 및 추출 등온선의 작성 및 최종적으로 추출제로부터의 탈거 조건을 확립하였다.
