マイナーアクチニド回収のための抽出クロマトグラフィ法において、効率的にマイナーアクチニドを分離するために吸着材中の錯体構造解析に係る研究を行っている。本研究では、マイナーアクチニドの模擬物質としてEuを使用し、シリカ担持型吸着材にEuを吸着させた試料を調製した。吸着材中のEu錯体の荷電粒子誘起発光スペクトルを測定し、Eu錯体構造解析に向けた基礎データを取得した。

In an extraction chromatography method for minor actinides recovery, analysis for the structure of complex in a silica-based adsorbent has been studied to separate minor actinides efficiently. In this study, Eu was used as simulated material of minor actinides, and silica-based adsorbents containing Eu complex were prepared. The ion beam induced luminescence spectra of Eu complexes in silica-based adsorbents were measured, and the basic data for the structures of Eu complexes were obtained.
