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 method and system combining filtration and ion-exchange structures for removing contaminants from liquids. In overall concept, contaminated liquid is passed through filtering mediums to remove particulate matter from the incoming contaminated liquid. Organics are removed from the liquid by passage through adsorbent non-ionic type resins. The liquid is then passed through strong acid cation exchange resins, weak base anion exchange resins, weak acid cation exchange resins, and strong base anion exchange resins arranged in a predetermined location in the liquid flow path to provide optimized contaminant removal. One of the optimization techniques is through the pH adjustment of the liquid at predetermined points in the flow path. Additionally, the liquid to be purified is passed through mixed bed polisher resins as well as chelation resins to provide a final substantially contaminant free liquid which is returned to use in a closed loop fashion.

Abstract: The present invention relates to ion exchange compounds on cellulose basis having formula ##STR1## wherein R is a group that forms chelate complexes with metal ions, and Cell stands for the cellulose matrix. Suitable functional groups R are derivatives of known metal reactants, which show a high degree of selectivity for specific metal ions. The ion exchange compounds are able to fix specifically preferred ions e.g. metal ions even in a considerable excess of foreign ions, for example in concentrated salt solutions.The improved ion exchange compounds of this invention are prepared by reacting the compound ##STR2## with cellulose in the presence of alkali, diazotizing the cellulose derivative resulting therefrom and subsequently coupling couplable compounds which form chelate complexes with metal ions.

Abstract: New chelate exchange resins capable of selective recovery of copper, nickel, and other valuable metals from an acidic aqueous leach liquor are prepared by reacting a crosslinked haloalkyl polymer matrix resin (I) with certain aminopyridines (II) to give a resin (III) ##STR1## with pendent methyleneaminopyridine groups attached to the matrix resin. Particularly useful resins are obtained by reacting chloromethylated styrene-divinylbenzene copolymer beads with an aminomethylpyridine, such as 2-picolylamine, N-methyl-2-picolylamine, N-(2-hydroxyethyl)-2-picolylamine, N-(2-methylaminoethyl)-2-picolylamine, or bis-(2-picolyl)amine. At a typical copper ore leach liquor pH of about 2, the picolylamine resins will absorb 15-30 mg copper/ml resin with a 5-10 fold selectivity for copper over ferric iron.
