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.

Abstract: In accordance with the present invention, an ion-exchange composition has been formed which comprises synthetic resin support particles, dispersant capable of suspending the support particles in an aqueous medium to inhibit or prevent agglomeration, and fine synthetic resin layering particles. In a preferred embodiment, the complex can be formed by contacting a suitable dispersant with monomer in an aqueous solution in which the monomer is insoluble. Under suitable conditions for suspension polymerization, the monomer will polymerize to form resin support particles having dispersant irreversibly attached to those particles. The dispersant is irreversibly attached to the synthetic resin support particles, either by covalent bonding or permanent physical entanglement. The dispersant is also attached to the fine layering particles, either by covalent bonding or electrostatic forces. The result is formation of a support particle-dispersant-layering particle complex.The novel ion-exchange composition can be made by forming a synthetic resin support particle-dispersant complex in which the dispersant is irreversibly attached to the support particles. The complex can then be mixed in aqueous slurry form with fine resin layering particles under conditions suitable to form a resin support particle-dispersant-resin layering particle complex in which the resin layering particles are irreversibly attached to the dispersant. In effect, the dispersant forms an irreversible bridge between the support and layering particles.

Abstract: Metal cations absorbed within a hydrogel chelation polymer are insolubilized for safe disposal by treating the polymer with a precipitative anion such as carbonate, aluminate, hydroxide, phosphate, silicate, or sulfide. Further insolubilization of the metal cations may be achieved by subsequent treatment of the polymer with a water-dilutable prepolymer composition such as phenol-formaldehyde resin, then heating to cause cross-linking of the prepolymer. The hydrogel chelation polymer, containing metal sulfide formed by virtue of the insolubilization process, is useful in abstracting from water metals whose sulfides are less soluble than the metal sulfide initially within the polymer.

Abstract: This invention relates to a method for improving the performance of liquidembrane separations by coating a liquid membrane onto solid ion-exchange resin beads in a fixed bed. Ion-exchange beads fabricated from an ion-exchange resin are swelled with water and are coated with a liquid membrane material that forms a film over the beads. The beads constitute a fixed bed ion-exchange column. Fluid being treated that contains the desired ion to be trapped by the ion-exchange particle is passed through the column. A carrier molecule, contained in the liquid membrane ion-exchange material, is selected for the desired ion in the fluid. The carrier molecule forms a complex with the desired ion, transporting it through the membrane and thus separating it from the other ions. The solution is fed continuously until breakthrough occurs at which time the ion is recovered, and the bed is regenerated.

Abstract: Powdered synthetic polymeric resin is produced by swelling or shrinking resin particles by contact with water or an organic solvent to introduce strain within the particles and comminuting the swollen or shrunk particles by grinding them in a rotary attrition mill. This process is particularly useful for the production of powdered resins for oral consumption, for example powdered cholestyramine resin, since particle sizes such that 90% by weight and/or number is below 30 microns in average particle diameter in the wet swollen state may be achieved.
