摘要：
The harmful effects of quinolone antibiotics on ecology and human health have attracted widespread attention. In this study, bamboo biochar synthesized at different pyrolysis temperatures was used to remove quinolone antibiotics (moxifloxacin (MFX), ciprofloxacin (CIP), and ofloxacin (OFLX) as models). The pyrolysis temperature of 700 degrees C led to a high pore volume and average pore size of biochar. The biochar produced at 700 degrees C presented high adsorption properties for MFX, CIP, and OFLX. The maximum adsorption capacities for MFX, CIP, and OFLX were 135.56, 151.31, and 116.40 mg/g, respectively. The adsorption performance could be described by the Langmuir isotherm model and pseudo-second-order kinetic model. Biochar produced from waste bamboo could be applied as low-cost environmental adsorbents for quinolone antibiotics removal.
