Ionosilicas as efficient adsorbents for the separation of diclofenac and sulindac from aqueous media†
Abstract
Mesoporous ionosilicas bearing ammonium groups appear as versatile adsorbent for anionic drugs. High amounts of the anionic drugs diclofenac and sulindac are irreversibly trapped within the materials whereas neutral species are hardly adsorbed. Our results open the route towards new ionic materials for wastewater treatment via ion exchange.
