摘要： Ionizable or polarizable, carrier-free radionuclides may be separated by electrofixation, from a low electric conductivity liquid target material in a flow cell fitted with a permanent electrode arrangement. The target liquid is separated while the fixing voltage is maintained; then the fixed radionuclide is removed again from the electrode, if required by heating, after switching off or reversing the poles of the field, after an optional intermediate rinsing.

摘要： The invention is both a system and method for continuously separating heavier from lighter isotopes of a particular element, such as zirconium. The system comprises a housing, a column assembly rotatably mounted with respect to the housing which includes a plurality of vertically oriented separation cells arranged in a circle, each of which contains a packing material, both a feed electrolyte source and a barren electrolyte source, each of which has an outlet mounted in the housing for continuously introducing either a feed electrolyte or a barren electrolyte into each of the cells as they rotate past the outlets, and upper and lower electrodes disposed over the upper and lower ends of the separation cells for inducing the electromigration of the lighter zirconium ions toward the lower ends of each of the separation cells. A drain assembly disposed beneath the column assembly continuously collects isotopic enriched electrolyte from the bottom ends of the separation cells. The speed of rotation of the column assembly is coordinated with the rate of eluant flow through the cells so that the same segments of the annular tray of the drain assembly continuously collect eluant enriched in a particular type of zirconium isotope.

摘要： A system providing excitation and selective transport and/or reaction of isotopologues. Two or more isotope effects are combined within a reaction cell to produce transient differentiation of isotopologues through excitation or chemical reaction followed by rapid separation or conversion. A current conductor adjacent to a fluid carries an excitation current produced by a switching source. The excitation current produces an alternating magnetic field adjacent to the conductor that interacts with a population of isotopologues within the adjacent fluid layer to produce a population of reaction intermediates or products that have an isotopic composition different from the initial isotopologues. An electrolytic power supply may also be connected to the conductor to provide a voltage that may be used to selectively attract and electrolyze a portion of the reaction intermediates or products within the adjacent fluid layer.

摘要： The invention relates to isotope separation methods, and methods for separating isotopes with low energy consumption, demonstrated using hydrogen isotopes. To this end, an isotope transfer electrochemical cell is provided, which comprises an anode plate and a cathode plate; current carrier plates with flow channels or mesh layers or porous material; a proton exchange membrane or solid polymer electrolyte membrane; and gas diffusion layers positioned on either side of the proton exchange membrane which together with the proton exchange membrane forms a membrane electrode assembly; and a housing containing the anode and cathode plates in operable arrangement with the membrane electrode assembly, and defining a hydrogen feed inlet on the anode, a product outlet on the cathode, an outlet for excess hydrogen on the anode, and internal flow paths for transfer of gases and fluids on either side of the membrane electrode assembly. Also described are methods for enriching or depleting the isotope present in the hydrogen gas/vapour feed e.g. for tritium removal, tritium enrichment and deuterium enrichment, by arranging a series of cells in a cascaded configuration.

摘要： A system providing selective spin modification and reaction in an electrolytic cell. An electrolytic cell is coupled to a magnet that provides a level-splitting magnetic field in a region of electrolyte adjacent to a working electrode, thus establishing a spin resonance for an unpaired electron associated with a chemical species in the region of electrolyte adjacent to the working electrode. The working electrode carries an excitation current produced by a switching source or amplifier. The excitation current produces an alternating magnetic field adjacent to the working electrode that alters the spin state population density for the unpaired electron associated with a chemical species within the electrolyte, thereby enhancing or inhibiting the reaction of the chemical species during subsequent electrolysis.

摘要： Ionisable or polarisable, carrier-free radionuclides may be separated by electrofixation, in a manner that is particularly well adapted to practical requirements, from a low electric conductivity liquid target material in a flow cell (1) fitted with a permanent electrode arrangement (2, 3). For that purpose, the target liquid is separated while the fixing voltage is maintained, then the fixed radionuclide is removed again from the electrode, if required by heating, after switching off or reversing the poles of the field, possibly after an intermediate rinsing. A cylindrical fixing electrode that forms the vessel casing with an axial counter-electrode shaped as capillaries that extend over the whole length of the cylinder and that at the same time supply the liquid medium are particularly appropriate. Field intensities in a range from 10 to 100 V/cm are appropriate. The flow cell may be integrated in the duct that extends from the nuclide generating station to the radiotracer synthesising apparatus, may form parts thereof or may be constituted by the reaction vessel of the synthesising apparatus. The apparatus is specially designed to extract 18F from H¿2?18O.
