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.

Abstract Traditionally, the removal of nitrogenous pollutants from wastewater relied on conventional anaerobic denitrification as well aerobic nitrification and anoxic denitrification. However, is complicated since it requires stringent environmental conditions a large land, therefore, were performed in two separate reactors. Although high pollutant efficiency has been achieved via denitrification, demerits this approach include operational costs. Other traditional nitrogen methods air stripping, reverse osmosis, adsorption, ion exchange, chemical precipitation, advanced oxidation process, breakpoint chlorination. Traditional are not only but they also uneconomical due to Researchers have discovered that can be carried out by heterotrophic nitrification‐aerobic (HNAD) microorganisms which remove single reactor does require operating conditions. Despite significant effort researchers put in, there still little information known about mechanisms antibiotic during HNAD. This review begins with an update current state knowledge antibiotics The HNAD examined detail. Followed by, enhancement co‐metabolism sulfamethoxazole (SMX) response microbial communities toxicity. Lastly, favorable for biodegradation examined. findings show SMX main mechanisms, pathways proposed discussion. research indicated potential wastewater.
