The Determination of Small Amounts of Thorium in Some Uranium Materials

Description: Abstract: "A method for the determination of small quantities of thorium in the presence of large quantities of uranium is presented. Solid samples are dissolved in an appropriate acid. Reducible metals are removed by means of a mercury cathode. Excess acid is removed by fuming to dryness. The residue is dissolved in water and made alkaline with saturated ammonium carbonate solution, thus complexing the uranium and permitting the precipitation of thorium hydroxide with the aid of an aluminum hy… more

A Determination of the U-235 Content in Highly Impoverished Material

Description: Introduction: "The product of a special run made in XAX was submitted to the Assay Department for a determination of the residual content of the 235 isotope. The charge material on this run was impoverished, with a ratio of approximately 1:2,000. The sample was submitted in the form of purified T3O8."

The Determination of Total Non-U Cations in UF₄ by Penta-Ether Extraction

Description: "In consideration of the known high efficiency of penta-ether on the extraction of [Uranium] from aqueous solution without particularly affecting most other cations in the solution, it was felt that a TNU (total non-U cation) determination could be based upon the use of pents-ether to remove the U from non-U cations. After such separation, the non-U cations could then be determined in essentially the same manner as in the present TNU method (Method 50, CD-3801). The use of the penta-ether separ… more

Column Adsorption Methods in Analytical Chemistry

Description: Technical report. Numerous application of various column adsorption techniques to inorganic analytical chemistry have appear in the literature. The comparatively recent introduction of ion exchange resins has resulted in the development of efficient, simple, and rapid column adsorption methods. the principal service of column adsorption methods to analytical chemistry is that of providing a relatively simple means of separating an element in a sufficiently pure state so that a direct precipita… more

The Laplacian for a Beryllium Metal Lattice of Volume Ratio 17.2

Description: Abstract. the Laplacian of a beryllium metal lattice with 3.3 kg of uranium metal per cell and a volume ratio of 17.2 was measured in the removable region of the CP-2 machine. the sandwich effect with different moderators made interpretation of the observations very uncertain. The best result found was Be = 407 x 10(-6) cm(-2).
