Title:
ウラン抽出サイクルにおける、硝酸水相（ＰＨＡＳＥＡＱＵＥＵＳＥＮＩＴＲＩＱＵＥ）から得られるウランからの化学元素の分離プロセス
Document Type and Number:
Japanese Patent JP5600002
Kind Code:
B2
Abstract:
A chemical element to be very efficiently separated from uranium starting from an acid aqueous phase, in an extraction cycle for the uranium, when this chemical element is present in said phase at a concentration less than that of the uranium, or even as a trace element, and when it is moreover less extractable by the extractant used in this extraction cycle than is the uranium. The chemical element can notably be neptunium(IV) or thorium 228.
