摘要：Embodiments of the present invention are directed to thermally regenerablesalt sorbent resins and methods of treating an aqueous fluid. Embodiments of themethod of the invention comprise contacting the aqueous fluid within a first temperaturerange with a mass of thermally regenerable salt sorbent resin comprising weak acidgroups with pKa between 4 and 6 and base groups having a pKb greater than 7.5. Incertain cases, the thermally regenerable salt sorbent resin comprises a first phasecomprising a host macroporous copolymer of a polyunsaturated monomer and amonoethylenically unsaturated monomer containing the weak acid groups and a secondphase comprising a crosslinked guest copolymer of a polyunsaturated monomer and amonoethylenically unsaturated monomer containing the base groups.
