1. A system comprising:
a separation medium for water purification including a silica-containing granular support, and an oligomeric or polymeric stationary phase coupled to individual grains of the silica-containing granular support, the oligomeric or polymeric stationary phase comprising oligomeric chains or polymeric chains covalently bound to the individual grains of the granular support, wherein the oligomeric chains or polymeric chains are covalently bound to silica moieties throughout bulk regions of the individual grains.
 
14. A system comprising:
a separation medium for water purification including a silica-containing granular support, and an oligomeric or polymeric stationary phase coupled to individual grains of the silica-containing granular support, the oligomeric or polymeric stationary phase comprising oligomeric chains or polymeric chains covalently bound directly to silica moieties of the individual grains via alkylene linkages.
