1. A separation medium for water purification comprising:
a silica-containing zeolite support; and
an oligomeric stationary phase coupled to individual grains of the silica-containing zeolite support, the oligomeric stationary phase comprising oligomeric chains covalently bound to silica moieties throughout bulk regions of the individual zeolite grains, wherein:
the individual grains have an average size range of 50 microns to 5,000 microns;
the oligomeric chains comprise 4 to 100 monomer units; and
the oligomeric chains include one or more cationic moieties for anion exchange and/or one or more anionic moieties for cation exchange.
