The Extraction of Uranium into Hexone as Uranyl Thiocyanate from Thorium Nitrate Solutions

Description: Technical report with six sections describing the process: (1) The reaction of HN)3 with HSCN; (2) The distribution of nitric acid between hexone and water; (3) The distribution of HSCN between hexone and water; (4) The solubility of thorium sulfate in various extraction solutions; (5) The distribution of protoactinium and fission elements between hexone and aqueous thiocyanate solutions; and (6) Separation of uranium from thorium by extraction into hexone as UO2(SCH)a.

Isotopic Examination of Tantalum

Description: Introduction: "The ionization region in the Nier mass spectrometer is customarily constructed of copper. Various other metals were tried for this purpose; among them tantalum and molybdenum, with both metals it was found that a spectrum of the fluoride of the metal appeared when uranium hexafluoride was admitted. It was thus possible to produce tantalum fluoride with comparative ease and to make a critical examination of the mass spectrum to set an upper limit of abundance of tantalum isotopes.… more
