Am、Cmや希土類元素の相互分離における陽イオン交換法の適用可能性を検討するために、スルホン酸基を交換基とするシリカ担持型陽イオン交換体 (SiSCR)を合成し、その熱分解特性及び希土類元素に対する吸着・溶離・分離特性を調べた。

In order to study the applicability of the separation of Am, Cm and rare earths from each other by cation exchange technology, a novel silica-based cation exchanger (SiSCR) with sulfonic acid group as exchange site has been synthesized. Its thermo-decomposition property and the performance of adsorption, elution and separation for some rare earths were investigated.
