The disposal and treatment of antibiotic residues is a recognized challenge due to the huge production, high moisture content, processing costs, residual antibiotics, which caused environmental pollution. Antibiotic contained valuable components could be recycled. Using one-step controllable pyrolysis technique in tubular furnace, biochar (OSOBs) was produced without preliminary carbonization step, innovative time- cost-saving compared traditional methods. main aim this study explore adsorption removal efficiency tetracycline (TC) water using porous prepared from oxytetracycline fermentation one step. A series characterizations were conducted on materials, effects dosage, initial concentration, reaction time, temperature capacity studied. experimental results showed that at 298 K, maximum OSOB-3-700 calculated by Langmuir model reached 1096.871 mg/g. kinetics fitting indicated more consistent with pseudo-second-order kinetic model, chemical adsorption. isotherm better described process biochar, indicating adsorbed monolayer specific homogeneous active sites through adsorption, conclusions. occurred surface containing rich sites, actions such as electron exchange promoted process.

Antibiotic contamination in aquatic environments is a growing concern, posing risks to public health and ecosystems. To address this issue, advanced materials like graphene oxide (GO) chitosan-based hydrogels are being extensively explored for their ability effectively remove antibiotics from wastewater, owing distinct characteristics synergistic benefits. This review comprehensively examines the synthesis, characterization, applications of GO/chitosan addressing antibiotic pollution. The synthesis methods, including solution casting, crosslinking, situ polymerization, discussed simplicity scalability. hydrogels' key properties, such as porosity, surface area, mechanical strength, essential efficient adsorption capabilities. Adsorption mechanisms, electrostatic interactions, π-π stacking, hydrogen bonding, functional groups, enable these achieve high capacities. Notable examples include rGO@ZIF-67@CS hydrogels, which achieved higher capacities 1685.26 mg·g−1 tetracycline at pH 4 1890.32 norfloxacin 5, while sulfonated CMC/GO-GCC composite hydrogel 312.28 sulfamethoxazole 298 K. Moreover, efficiencies 90.42% with GO–CTS 97.06% were using AGO–CTS diclofenac adsorption. also highlights practical wastewater treatment, comparing performance other adsorbents challenges scalability regeneration. Finally, explores future research directions enhance effectiveness sustainability emphasizing potential scalable, eco-friendly solutions removal water.
