摘要： A method for producing a metal ion exchanger with increased absorption and regeneration capabilities that comprises treating an ionically inert porous support with a solution of metal oxychloride. Said metal oxychloride precipitates within the pores of the support and bonds thereto regardless of the pH of the system. The ion exchanger is then used as a medium through which sea water or other brine solutions are passed and inorganic ions and trace organics selectively absorbed. The ion exchanger is easily regenerated after absorption through treatment with sodium hydroxide and hydrochloric acid and can be reused immediately.

摘要： Porous granules that contain separate particles of alkali metal silicate and zeolite are stable and are efficient ion exchangers in aqueous effluents and/or solutions. Said granules are heated to provide the stability required so that even though some silicate may dissolve when the granules are exposed to water, the zeolite does not disperse throughout the water.

摘要： A method is disclosed for encapsulating and solidifying spent ion exchange beads contained in a container to form an ion exchange bed with a solidification resin without the necessity for applying shear in the bed by an external force such as by a mixing impeller. A solidification resin is flowed through the ion exchange bed by plug flow to intermix with and encapsulate each ion exchange bead therein. The resin is cured to form a uniform, solidified monolith of said ion exchange beads in said container. When the ion exchange bed contains free water, the process also effects the removal of substantial portions of the free water and also emulsifies and solidifies free water remaining in the bed.

摘要： Apparatus for gathering valuable substances, such as uranium, gold, silver or the like from sea water. The features characterizing the invention are that the sea waves are caused, by using the energy thereof, to rush up a ramp (2) which leads the waves into a basin from above, which thereby is filled to a level (B.sub.Y) higher than the external still-water surface (L.sub.Y), the water quantity within the level difference (.DELTA.H) applying a hydrostatic pressure which brings the water in the basin to flow through one or several layers of filters (4) containing sorbing, ion-exchanging or bioactive mass, whereafter the water is directed back to the sea on a level lower than the upper edge of the ramp (2).

摘要： An improved tracer particle is described comprising an ion exchange core having a polymer coating thereon, the coated ion exchange core having a reaction site capable of reacting with a compound containing an oxirane group, said coated ion exchange core having been treated with a compound containing an oxirane group to react with said coated ion exchange core causing an increase in mass of the tracer particle. Preferably, the ion exchange core is labelled with a radionuclide. These particles have improved characteristics including improved stability against leaching and improved handling properties. Such particles are useful in circulatory determinations involving the injection of the particles as a suspension in a physiologically acceptable carrier or medium into the circulatory system of animals.

摘要： An organic ion exchange material, which comprises a mixture of grains of a first type bearing groups containing exchangeable hydrogen ions and grains of a second type bearing groups containing exchangeable hydroxyl ions and which has been used in a cleaning circuit in a nuclear reactor, is subjected to a treatment before the ion exchange material is further processed for final storage of the radioactive waste products contained therein. The treatment comprises removing hydrogen ions and/or hydroxyl ions or groups containing hydrogen ions and/or groups containing hydroxyl ions from the grains, whereafter the grains of the first type are separated from the grains of the second type, before the grains of each type are further processed separately for final storage of the radioactive waste products contained therein.

摘要： High density, ion exchange resins having excellent integrity are prepared from cross-linked, aromatic polymers which have been halogenated in the presence of an organic liquid having a sufficiently high dielectric constant to prevent substantial halogenation of the polymer backbone such as various organic nucleophiles having a free electron pair associated with a nonhalogen atom, e.g., ethanol or dimethylformamide. For example, a cross-linked polystyrene which has been brominated in methylene chloride containing a small amount of ethanol can subsequently be chloromethylated and aminated to form a high density anion exchange resin useful in removing anions from thick slurries such as those employed in uranium recovery.
