    Abstract: Proposed is a method for the preparation of an efficient ion exchanger useful for separation and recovery of cesium ions from an aqueous solution such as strongly acidic waste solutions containing radioactive species of cesium. The method comprises the steps of (a) adsorption of hexacyanoferrate (II) ions on to porous particles of an anion exchange resin, (b) conversion of the hexacyanoferrate (II) ions into water-insoluble copper salt thereof in situ in the resin pores, (c) an oxidation treatment of the resin particles and (d) a reduction treatment in the presence of potassium ions followed by contacting of the resin particles with an aqueous solution containing copper ions. A method for the regeneration of the ion exchanger after adsorption of cesium ions is also proposed.

    Abstract: For the conditioning of ion exchange resins, pure water is recirculated over a bed of the resin to be purified or of the resins to be purified. The pure water has a residual salt content of less than 50 ppb and a content of free acids or free bases of less than 5,000 ppb. The organic and inorganic substances washed out of the resin or the resins are removed continuously from the circulating water by methods for the purification of water. The process can be used for conditioning the ion exchange resins used in an ultra pure water production system.

    Abstract: A process for selectively removing anions from an aqueous solution involves contacting the solution for an effective period of time with a specialized polymer in a porous format. The polymer has ligand sites capable of forming coordination or complexation bonds with multi-valent metal cations which serve to activate the polymer with respect to chemical interaction with anions. The polymer, saturated with the multivalent metal cations, contains between 2% and 20% of metal cation based upon the dry weight of the polymer.

    Abstract: Microporous anionic exchange and non-ionic adsorbent resins which are capable of adsorbing an antibiotic and which have been coated with a non-ionic detergent are disclosed. When contacted with bacterially infected body-fluid specimens, the disclosed resins remove antibiotics from the specimen while exhibiting diminished bacterial adsorption. A combination of a disclosed detergent-coated non-functional adsorbent resin with a cationic resin removes other bacterial inhibitors, as well as antibiotics, from bacterially infected body fluid specimens while permitting the bacteria to remain in the specimens. By removing bacterial inhibitors while sparing the bacteria, the disclosed resins make possible rapid isolation and identification of an infecting organism.
