{sup 232} Th - {sup 233} Pa separation by extraction chromatography

Miscellaneous:

Abstract

Thorium and protactinium behavior in extraction chromatography systems is presented, aiming its separation by selective retention of the micro constituent on the column. TBP/alumina, TBP/voltalef UF 300, TOA/alumina and TOA/voltalef UF 300 systems were verified. Column preparation as well the {sup 233} Pa removal conditions were settled. The best {sup 232} Th separation from its irradiation product, {sup 233} Pa, has been achieved by using TBP/voltalef UF 300 system. {sup 233} Pa was selectively retained on column from 10 M HCl solutions and eluted with 3 M HCl.
