Nuclear Rare Metals and their Separation in Advanced ORIENT Cycle Strategy

摘要

New concept of nuclear rare metals was proposed. Hydrometalhrrgical separations of such nuclear rare metals have been progressed in the frame of strategic Advanced (Adv.-) ORIENT Cycle research in Japan. A hybrid separation system by ion exchange chromatography (KC) and catalytic electrolytic extraction (CEE) will meet well with the concept of Green Chemistry, thereby being proposed as a vital separation tool for light PGM (Ru, Rh, Pd), Tc and f-elements. Adv.-ORIENT Cycle process can not only improve the rad. waste problem, but also offer useful rare metals to the leading industries as for the second resource.
