    摘要： 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.

    摘要： A process for the production of a particulate ion exchange material which comprises heating an inorganic material to produce a porous inert inorganic substrate, adsorbing an organic monomer into the substrate and polymerizing the adsorbed monomer so that the resultant polymer is retained within the pores of the substrate, and, if necessary, introducing ion exchange functional groups into the polymer.

    摘要： A process for absorbing silver from photographic hypo solutions involves passing the hypo solution through a bed consisting of a multitude of a sponge product confined within a vessel. The sponge product is derived from an open-celled cellulosic sponge into which there has been incorporated 30% to 80% by weight of a polymer produced by the thermal interaction of polyethyleneimine (PEI) with a polycarboxylic acid. The polymer further contains an activating multivalent cation and between 90% and 300% water. Silver is eluted from the sponge product employing aqueous solutions of a complexing agent such as an ammonium compound or a cyanide compound. Following a water wash, the bed of sponge product is ready for its next cycle of silver absorption.

    摘要： 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.
