Abstract：In recent years,antibiotic pollution has become a global environmental issue.The accumu-lation of antibiotics in water not only threatens the stability of ecosystems but also increases the risk of the spread of antibiotic resistance genes,posing a long-term hazard to human health.Therefore,developing efficient and environmentally friendly technologies to remove antibiotics from the environ-ment has become an important research focus.Biochar,a stable porous carbon material produced from the pyrolysis,gasification,or hydrothermal carbonization of biomass,possesses a high specific surface area and rich surface functional groups,demonstrating significant antibiotic removal capabilities.Studies have shown that biochar can achieve removal efficiencies exceeding 90％for sulfonamides,tet-racyclines,and quinolones.This paper reviews the research progress of biochar in the field of antibi-otic removal,analyzing its preparation and modification technologies,removal effects,and mecha-nisms of action,while also discussing the key factors influencing removal efficiency.Despite its prom-ising potential in antibiotic remediation,biochar still faces challenges such as high costs and insuffi-cient long-term stability.
