    Abstract: Shreds of a treated cellulosic paper are randomly gathered as an aggregation which permits passage of water. The paper contains chemical functionality which selectively absorbs dissolved ionic metal species from water. This invention is based in part upon the discovery that a protonated form of PEI, created by addition of acid species to PEI (to produce a pH in the range of 4.5 to 6.8), can undergo thermally induced chemical reaction with cellulose to impart ion exchange properties without decomposition. Furthermore, by utilizing PEI of exceptionally high molecular weight, cellulose substrates thus treated, particularly paper and paper pulp, have sufficient ion exchange capacity to be of commercial value; for example, and not by limitation, they can be shredded and formed into aggregations providing specialized performance in fixed bed absorption operations.

    Abstract: An ion exchange polymer is provided. The ion exchange polymer is a reaction product of a reaction between a crosslinker monomer and a cationic monomer. The crosslinker monomer is a reaction product of a reaction between a first crosslinking monomer and a second crosslinking monomer. Further, the cationic monomer comprises a quaternary ammonium group. A method for making an ion exchange polymer is also provided. The method comprises a step of preparing a curable solution and a step of curing the curable solution. The step of preparing the curable solution comprises mixing a pair of crosslinking monomers, a cationic monomer that comprises a quaternary ammonium group and an acid. A membrane is also provided. The membrane comprises the ion exchange polymer made by the method provided.
