- 中文摘要: If a mixture of nitrates of thorium, cerium and rare-earths in 6 N nitric acid was allowed to pass through a column containing anion exchange resins of Amberlite JRA-400 in nitrate form, thorium could be sharply separated from rare-earths including cerium. It seemed that thorium might form thoric nitrated complex anion, for they could be retained quantitatively. Although ceric cerium was known to form complex nitrato-cerate anion in 6 N nitric acid, it could not be retained but was washed out from the column with the other rare-earths, owing probably to the reduction of ceric ion by the resins.
