Super-adsorbent microspheres based on a triallyl isocyanurate–maleic anhydride copolymer for the removal of organic pollutants from water

Cationic nanoporous microspheres were designed for the removal of diclofenac sodium, and they showed a rapid adsorption rate (reached equilibrium within 30 min), a high equilibrium adsorption capacity (1421 mg g −1 ), and excellent recyclability.
