The Distribution of Impurities in the Ether Extraction Process

Description: When uranium is purified by the ether extraction method, black oxide is dissolved in nitric acid and ether is added; an ether layer containing uranium and an aqueous layer containing uranium and impurities are obtained. The distribution of some impurities between the two phases and the effect of such impurities on the extraction process were studied. the processing required in the preparation of pure uranyl nitrate might be decreased if, instead of uranosic oxide, sodium diuranate was used as a… more

Design, synthesis, and characterization of novel fine-particle, unsupported catalysts for coal liquefaction

Description: The first task in our proposed study of catalysts for coal liquefaction was to prepare ultrafine dispersed metal sulfide particles by reactive precipitation from solutions of appropriate metal precursors. At this point, equipment to allow us to prepare these air-sensitive materials in an anaerobic environment has been acquired and assembled. Initial experiments aimed at synthesizing iron sulfide particles have been initiated. As part of the investigation of short contact time catalytic coal liq… more
