Abstract

The sorption and desorption behaviour of several radionuclides, including 241Am, 152,154Eu, 233U, 137Cs, 90Sr and 90Y was studied under varying acidities using zirconium vanadate as ion exchanger. The sorption follows the order: Cs > Eu > Am >Y > U, while Sr was not taken up by the ion exchanger. A radiochemical separation scheme for the 90Y daughter from its 90Sr parent using zirconium vanadate ion exchanger has been developed. The exchanger was synthesized and characterized in our laboratory.

摘要

使用钒酸锆作为离子交换剂，研究了几种放射性核素（包括241Am、152,154Eu、233U、137Cs、90Sr和90Y）在不同酸度下的吸附和解吸行为。吸附顺序为：Cs＞Eu＞Am＞Y＞U，而该离子交换剂不吸附Sr。已经开发出一种使用钒酸锆离子交换剂从其母体90Sr中分离90Y子体的放射化学分离方案。该离子交换剂在我们实验室中合成并进行了表征。
