Hydrophobic-hydrophilic interpenetrating polymer networks (IPNs) composed of hydrophobic polystyrene (PST) and hydrophilic polyacryldiethylenetriamine (PADETA) networks and their high efficient adsorption to salicylic acid.

Herein we synthesized a kind of novel hydrophobic-hydrophilic interpenetrating polymer networks (IPNs) composed of hydrophobic polystyrene (PST) and hydrophilic polyacryldiethylenetriamine (PADETA) networks, and the as-prepared PST/PADETA IPNs possessed both hydrophobic-hydrophilic property and medium high Brunauer-Emmett-Teller (BET) surface area, and hence bringing to much greater adsorption to the hydrophobic-hydrophilic adsorbate like salicylic acid. Particularly, PST/PADETA IPNs were much superior to some other adsorbents reported in the literatures. [ABSTRACT FROM AUTHOR]
