Eliminating different pharmaceutical contaminants simultaneously from wastewater has become a crucial environmental issue. In this regard, the shift from the conventional methods of removing single pollutant to implementing a system that simultaneously removes multiple contaminants is required. In pursuit of this goal, functionalized biochar (FBC) was prepared from bamboo sawdust to simultaneously remove pharmaceutical pollutants in batch and fixed-bed sorption systems. FBC exhibited a greater removal capacity for acetaminophen (ACM) (192.43 mg/g) compared to ciprofloxacin (CIP) (70.95 mg/g), as predicted by the Langmuir isotherm model. The competitive Langmuir isotherm model, employed for the binary component, predicted a maximum adsorption capacity of 125.31 mg/g for ACM and 65.44 mg/g for CIP. The adsorption capacity ratio (qm binary/qm single
