摘要： The present invention provides methods for separating isotopes of actinide elements such as uranium using microorganisms, e.g., metal or sulfate reducing bacteria. The microorganisms reduce the actinide element to form a precipitate, which contains a greater proportion of the lighter isotope relative to the heavier isotope than the starting material. The precipitate may be collected, re-oxidized, and subjected to multiple rounds of enrichment. Alternately, separation processes not requiring formation of a precipitate may be used. The invention also features cell-free systems for isotope separation. The invention further provides compositions produced according to the foregoing methods, including compositions comprising enriched uraninite.

摘要： Uranium metal can be electrochemical deposited from room temperature ionic liquid (RTIL), tri-methyl-n-butyl ammonium n-bis(trifluoromethansulfonylimide) [Me3NnBu][TFSI] providing an alternative non-aqueous system for the extraction and reclamation of actinides from reprocessed fuel materials. Deposition of U metal is achieved using TFSI complexes of U(III) and U(IV) containing the anion common to the RTIL. TFSI complexes of uranium were produced to ensure solubility of the species in the ionic liquid. The methods provide a first measure of the thermodynamic properties of U metal deposition using Uranium complexes with different oxidation states from RTIL solution at room temperature.
摘要翻译：铀金属可以从室温离子液体（RTIL），三 - 甲基 - 正丁基铵正 - 双（三氟甲烷磺酰亚胺）[Me3NnBu] [TFSI]进行电化学沉积，提供了一种替代非水系统，用于从锕系元素中提取和回收锕系元素再加工燃料。使用含有与RTIL共有的阴离子的U（III）和U（IV）的TFSI复合物实现U金属的沉积。制备铀的TFSI络合物以确保物质在离子液体中的溶解度。该方法提供了使用在室温下从RTIL溶液中具有不同氧化态的铀络合物的U金属沉积的热力学性质的第一测量。
