    摘要： An aqueous solution of hydroxylamine sulfate and a solution of nitric acid are each circulated from tanks (5, 6) through alternate adjacent chambers in an electro­dialysis cell (2) or diffusion dialysis cell, the chambers being separated by cation exchange membrane (1); dialysis occurs so that NH₃OH⁺ and H⁺ ions pass through the membrane and the nitric acid is converted to hydroxylamine nitrate product. The solutions are recirculated by pumps (7, 8). In the hydroxylamine sulfate solution, the SO₄⁻⁻ anions remain, and since the H⁺ ions permeate thereinto, sulfuric acid is formed; and at a concentration of above 0.2 N the SO₄⁻ ion passes through the membrane and would contaminate the product. The NH₃OHNO₃ solution is therefore circulated simultaneously into a diffusion dialysis cell (22) having a number of anion exchange membranes (21); pure water is circulated countercurrently through alternate chambers in the cell (22) to remove the acid.

    摘要： Ammonium metatungstate is produced by contacting the anolyte side of a cation exchange membrane with an aqueous solution of ammonium tungstate and applying an electrical potential across the membrane such as to effect the transport of ammonium ions from said solution through the membrane to lowerthe pH of the solution to a level at which ammonium metatungstate is formed.

    摘要： A fluorinated graphite having the formula (C x F) n wherein x is a numerical value of about 2.0 to about 5.5 and n refers to an indefinite number of the recurring (C x F) unit and having a crystalline structure exhibiting a peak at about 13.7° to about 15.0° in terms of an angle of 26 corresponding to the diffraction at the (001) plane in the X-ray diffraction pattern, a peak in the vicinity of 685.3 eV due to the F 1S and two peaks in the vicinity of 287.5 eV and 284.3 eV due to the C 1S in the spectrum of electron spectroscopy of chemical analysis, two peaks in the vicinity of 1100 cm- 1 and 1240 cm -1 in the IR spectrum, and an electric conductivity of at least about 10- 8 Ω -1 cm -1 , and being thermally stable in air up to 200°C from the viewpoint concerning a pattern of X-ray diffraction; a process for producing the fluorinated graphite thereof which comprises subjecting a carbon material to electrolysis in hydrogen fluoride at a voltage of about 6.5 V to about 15 V at a temperature of about -40°C to about 100°C in the presence of an electrically conductive agent; and an electric cell comprising a negative electrode using a light metal as an active material, an electrolyte and a positive electrode using, as an active material, the fluorinated graphite. The fluorinated graphite has a wide variety of uses, for example, besides as an active material for the positive electrode of an electric cell as above, lubricants, stain-resistant and water and/or oil repellent materials, etc. The electric cell as above is advantageously used in devices requiring a high voltage such as a watch, a clock, a small radio, a small computer, etc.

    摘要： A process is disclosed for dissolving PuO 2 , or nuclear reactor fuel containing P U 0 2 and/or Np0 2 , in an aqueous medium containing nitric acid. The process comprises electrolytically continuously maintaining and regenerating an oxidizing reagent, being at least one compound of Ce, Ag, Co or Am which is soluble in the said medium. The regenerable reagent may be added to the mixture of oxide(s) and nitric acid, or may already be present in situ as a fission product or other nuclear reaction product in irradiated nuclear reactor fuel.
