Functionalization of graphene nanostructures with inorganic nanoparticles and their use for the removal of pharmaceutical pollutants in water

Emerging pollutants such as pharmaceuticals are of special concern because despite their low environmental concentration, biological activity can be intense, and they should prevented to reach uncontrolledly the environment. A graphene-based hybrid material decorated with Fe 3 O 4 TiO 2 nanoparticles (NPs) has been prepared effectively remove emerging nonsteroidal anti-inflammatory drugs (NSAIDs) Ibuprofen Diclofenac present in water at concentrations by a one-step functionalization process following novel gentle scalable surfactant depletion approach. Following this methodology, progressively deprived original presence graphene, leading formation nanostructures composed two different types well dispersed over graphene nanosheets. adsorption kinetics on composites was investigated via UV-Vis spectroscopy. The possesses high capacity, superparamagnetic properties, photocatalytic behavior, good dispersibility. Thanks incorporating situ catalysts, performance is restored after use, which could promising recycling pathway for adsorbents wastewater treatments.
