Abstract:
The invention includes ion exchange resins and their use in the removal of chromium from water. In one embodiment, the invention comprises a method for removing chromium from a water source by contacting the water with an ion exchange resin, wherein the ion exchange resin comprises particles of a crosslinked copolymer comprising: an interpenetrating polymer network (IPN) of at least two polymer components each having a styrenic content greater than 50 molar percent, and a quaternary ammonium functionality.
