摘要： In one aspect, separation media are described herein operable for removing one or more water contaminants, including NOM, fluorinated chemicals, and/or derivatives thereof. Briefly, a separation medium comprises a silica-containing granular support; and an oligomeric stationary phase forming a film on individual grains of the granular support. In some embodiments, the oligomeric stationary phase comprises oligomeric chains covalently bound to the individual grains.

摘要： In one aspect, separation media are described herein operable for removing one or more water contaminants including NOM and derivatives thereof. Briefly, a separation medium includes a nanoparticle support and an oligomeric stationary phase forming a film on individual nanoparticles of the support, the film having thickness of 1 to 100 nm. In some embodiments, oligomeric chains of the stationary phase are covalently bonded to the individual nanoparticles.
