摘要： The widespread presence of antibiotics in the aquatic environment has caused major ecological problems, which is due to their complex and lasting chemical properties. The advanced oxidation process (AOPs) is known for its powerful effectiveness and has become the best solution for treating wastewater containing antibiotics. Iron-based biochar composite materials (Fe@BC) are low-cost and have excellent surface physicochemical properties, and perform well in water pollution control. This article discusses the latest progress in the field of Fe@BC application, covering synthesis technology, performance evaluation, practical application and pollutant removal strategy. Various preparation methods of Fe@BC composites have a significant impact on their chemical and structural characteristics, which in turn determine their pollutant removal efficiency. Fe@BC can achieve the removal of antibiotics through a variety of ways such as adsorption, oxidation and reduction. These processes involve complex interactions, including hydrogen bonding, π-π electron receptor interaction, electrostatic attraction and the formation of reactive oxygen species (ROS), such as sulfate radical free radicals and hydroxyl free radicals. The overview shows that in order to improve the efficiency of pollutant removal, it is necessary to optimize synthetic parameters, such as biomass type, pyrolysis temperature, iron precursor ratio and reaction medium. The study emphasizes the importance of understanding the scale operation mechanism of technology and dealing with the ensuing problems. Future research should focus on improving the synthesis method, clarifying the response path, and integrating Fe@BC into the overall plan of environmental governance.
