Abstract: Provided are methods of removing perchlorate from water. The methods include contacting water suspected of containing perchlorate with a cationic material. The cationic material includes one or more cationic metal atoms connected by an atom or molecule into an extended structure, and a charge balancing anion. The contacting removes perchlorate (e.g., selectively), if present, from the water. Water treatment vessels, systems and facilities that find use in practicing the methods of the present disclosure are also provided.

Abstract: Anion exchange polymers comprise a plurality of repeating units of formula (I). The polymer may be synthesized from a super acid catalyzed polyhydroxyalkylation reaction of monomers Ar1′, Ar2′, and X1′ to form a neutral precursor polymer followed by a Menshutkin reaction to convert the neutral precursor polymer to the anion exchange polymer.
Anion exchange membranes and membrane electrode assemblies incorporating the anion exchange polymers are also described.-

Abstract: A method for synthesizing a poly(phenylene) with high ion selectivity comprises dissolving an alkyl halide poly(phenylene) in a polar aprotic solvent to form a nonaqueous solution and adding an anhydrous nucleophile to the nonaqueous solution to replace the halide of the alkyl halide poly(phenylene) with a cationic group of the nucleophile. The poly(phenylene) can be used in anion exchange membranes.

Abstract: An ion-exchange composition suitable for use in ion exchange chromatography, comprising neutral vinyl polymer support particles irreversibly bound to a dispersant having ionizable sites which are un-ionized at a neutral pH and which are ionized under highly acidic or highly basic conditions, and fine layering particles functionalized with ion-exchanging sites on the surfaces thereof. A portion of the ionizable sites are ionized and bound electrostatically to a portion of the fine layering particles ion-exchanging sites, producing a support particle-dispersant-fine layering particle complex.
