用汞阴极从含有醋酸和乙酸钠的水溶液中定量地制备了铀汞齐。银汞合金的热分解得到了亮的金属铀按钮或棕色的多孔铀金属按钮。纯度远高于99.95%左右的工业级金属。作为这项工作的结果，已经开发出在实验室规模上制备高纯度金属铀的简便方法。
The uranium amalgam was quantitatively prepared by electrolysis from the aqueous solution containing acetic acid and sodium acetate using a mercury cathode. A bright button or brown porous one of uranium metal was obtained by thermal decomposition of the amalgam. The purity was found to be much higher than commercial grade metal of ca. 99.95%. As a result of this work, the simple and easy procedure for preparation of uranium metal with a high level of purity on the laboratory scale has been developed.
