摘要： Method of making an ion exchange material in which a ceramic material is ion-implanted with sulfur, carbon, phosphorus, or nitrogen, which is oxidized to sulfate, carboxylate or carbonate, phosphate, or nitrate, respectively, or the nitrogen is reduced to amine or amide. Alternatively, a mixture of ceramic powder and a binder containing sulfur, carbon, phosphorus or nitrogen is heated in a non-oxidizing atmosphere to a temperature up to 1000°C. The sulfur is then oxidized to sulfate, the carbon to carboxylate or carbonate, phosphorus to phosphate, and nitrogen to nitrate, or the nitrogen is reduced to amine or amide. Also a method of treating acidic aqueous solutions containing dissolved radioactive materials by passing them through an ion exchange column containing the ion exchange material made by the afore-mentioned methods.

摘要： @ A method of decontaminating metal surfaces having a ra- dicactive coating thereon where the coating contains metal tons, uses an aqueous decontamination solution containing at least one chelate which is passed over the coating to solubilize the metals. The solution is then passed through a porous direct current electrode to reduce the metal ions in the solution; the solution is again passed over the coating. An apparatus for decontaminating metal surfaces using the inventive method includes means for circulating the aqueous decontamination solution among the porous cathode, and the metal surfaces and a container which stores the aqueous decontamination solution.

摘要： The isotopes of zirconium can be partially or completely separated by loading an essentially anhydrous alcoholic solution of an ionic compound of zirconium onto a cationic exchange resin with pentavalent phosphorus derived active groups which serves as the stationary phase of a chromatograph, eluting the compound with an essentially anhydrous alcoholic solution of hydrogen chloride and collecting distinct elution volumes representative of each isotope. In a preferred embodiment, the active groups of the cation exchange resin are derived from di-2-ethylhexyl phosphoric acid, tri-n-octyl phosphine oxide or tributyl phosphate and the chromatograph is of a type, such as a continuous annular chromatograph that it can be operated in a continuous, steady state manner.

摘要： Process of producing nickel suboxide insulation on a superconductor by reacting oxygen-free nickel powder with oxygen-free carbon monoxide generally at 50-75°C to produce a nickel carbonyl, separating the nickel carbonyl from reaction by-products and excess reagents by cooling the carbonyl and decanting the nickel carbonyl liquor, and contacting the carbonyl to a surface of a wire containing superconductor or superconductor precursors in an atmosphere containing a controlled amount of oxygen, with the wire at 50-800°C to produce nickel suboxide insulation on the wire. The purified nickel carbonyl and oxygen may be alternately (rather than simultaneously) introduced, to deposit a series of metallic nickel films on the wire, each of which metallic films are then oxidized to a nickel suboxide.

摘要： A method and apparatus for electrolytically removing radioactive metal ions from a decontamination solution to regenerate the solution and prepare the ions for disposal are disclosed herein. At least the cathodic portion (69) of the electrode (45) used in the electrolysis is formed from a combustible material, such as a semi-fluidized bed of graphite particles. In the method of the invention, the decontamination solution is passed in intimate contact with the graphite particles forming the cathodic portion (69) of the electrode (45) as an electric potential is applied to the electrode (45). As a result of the electric potential, the metal ions are detached from the chelate in the decontamination solution and deposited onto the graphite particles of the cathodic portion (69) of the electrode (45). After the electrode (45) becomes spent, it is incinerated in order to reduce the volume of the resulting radioactive ash. The gases produced from the incineration are scrubbed with a scrubbing liquid to remove radioactive particles therefrom. The contaminated scrubbing liquid is in turn used to form a cementitious substance or grout which encapsulates the radioactive ash.
摘要翻译：本文公开了一种从去污溶液中电解去除放射性金属离子以再生该溶液并制备用于处置的离子的方法和装置。至少电解用电极（45）的阴极部分（69）由可燃材料形成，例如石墨颗粒的半流化床。在本发明的方法中，当将电位施加到电极（45）上时，去污溶液与形成电极（45）的阴极部分（69）的石墨颗粒紧密接触。作为电位的结果，金属离子与去污溶液中的螯合物分离并沉积到电极（45）的阴极部分（69）的石墨颗粒上。在电极（45）耗尽之后，它被焚烧以便减少所产生的放射性灰分的体积。由焚烧产生的气体用洗涤液洗涤以从其中除去放射性颗粒。污染的洗涤液又用于形成包封放射性灰分的胶结物质或浆料。
