Graphene oxide–chitosan composites are attracting considerable interest as an eco-friendly adsorbent material for most aquatic environmental pollutants. Today, the focus is on emerging applications of 2D and 3D graphene functionalized with chitosan to enhance its mechanical properties adsorption efficiency. Herein, super (3D GF-CS) synthesized remove sulfamethazine, (SMZ) a model antibiotic pha...
