Abstract: 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.

Abstract: An ion exchange composition formed of insoluble synthetic resin support particles with ion exchange sites at their exposed surfaces, and fine synthetic resin layering particles with ion exchange sites on their exposed surfaces, which attract the ion exchange sites of the support particles so that the layering particles are irreversibly attached as a monolayer to the support particles. The layering particles have a median diameter ranging from 0.002 to 0.09 microns, while the ratio of median diameters of the support particles to layering particles range from 100 to 1, and 5000 to 1. The composition is packed into a column and is used for separation of ions in liquid ion exchange chromatography.

Abstract: Ion exchange resins exhibiting increased crush strength and/or higher density are prepared from a cross-linked polymer by imbibing a halo-substituted olefin within the cross-linked polymer's structure and subsequently polymerizing the imbibed olefin. For example, imbibing vinylidene chloride within a chloromethylated, cross-linked copolymer of styrene and subsequently polymerizing the vinylidene chloride forms a high density resin, which resin is useful in the preparation of ion exchange and chelate type resins having improved crush strength.

Abstract: A process for removing pollutants or minerals from lake, river or ocean sediments or from mine tailings is disclosed. Magnetically attractable collection units containing an ion exchange or sorbent media with an affinity for a chosen target substance are distributed in the sediments or tailings. After a period of time has passed sufficient for the particles to bind up the target substances, a magnet drawn through the sediments or across the tailings retrieves the units along with the target substance.

Abstract: A method for forming agglomerated ion exchange particles in which finely divided synthetic resin coating particles are affixed to the surface of synthetic resin substrate particles. The surface of the coating particles have ion exchange sites with monovalent counterions (e.g., negatively charged) which are attracted to the ion exchange sites on the substrate particles. Multivalent ions (e.g., carbonate) of the same charge as such monovalent counterions are mixed into an aqueous disperson of the coating particles to displace the monovalent counterions thereby increasing the electrostatic charge density of the coating particles. Then, a slurry of the synthetic resin substrate particles is added dropwise to this dispersion which is mixed to form agglomerates by electrostatic attraction.
