Adsorbent Pollutant Adsorption capacity Reference Significant findings Embedded GO aerosols. Coated GO aerosols Ofloxacin, ciprofloxacin, and Pb2+ 5-8 mg/g for antibiotics for both adsorbents. For Pb2+ : 11.1 mg/g for embedded GO aerogels and 1.5 mg/g in coated GO ones [27 ] Antimicrobial effects were found particularly for the GO-coated aerogel materials Graphene oxide (GO) Tetracycline antibiotics 313 mg/g [54 ] Tetracycline strongly deposited on the GO surface via interaction and cation– bonding. Nanostructured porous graphene Atenolol (ATL), ciprofloxacin (CIP), carbamazepine (CBZ), ibuprofen (IBP), diclofenac (DCF), and gemfibrozil (GEM) 8.87, 7.33, 14.63, 47.85, 91.59, and 9.26 mg/g, respectively [56 ] (i) Regeneration and reuse for four cycles (ii) Heterogeneous adsorption described by the Toth and Sips isotherm models Graphene oxide Metformin 96.7 mg/g [57 ] Graphene oxide nanoplatelets Carbamazepine (CBZ) 9.2 mg/g [58 ] Could be reused for up to 8 times Graphene oxide composite with activated carbon and chitosan Acetaminophen (ACP), carbamazepine (CBZ), bisphenol A (BPA), caffeine (CAFF), and triclosan (TCS) 13.7, 11.2, 13.2, 14.8, and 14.5 mg/g, respectively [59 ] According to DFT studies, the adsorption process is mostly accompanied by size-related diffusion, with a modest contribution from a synergetic mix of hydrophobic/hydrophilic, hydrogen bonding, electrostatic, and interactions Reduced graphene oxide (rGO)–cellulose nanocrystal sponge Methylene blue 17 mg/g [60 ]
