Due to increasing antibiotic pollution in the water environment, green and efficient adsorbents are urgently needed solve this problem. Here we prepare magnetic bamboo-based activated carbon (MDBAC) through delignification carbonization using ZnCl2 as activator, resulting production of an with large specific surface area (1388.83 m2 g-1). The influencing factors, such solution pH, initial sulfadiazine (SD) concentration, temperature, contact time, were assessed batch adsorption experiments. Langmuir isotherm model demonstrated that MDBAC capacity on SD was 645.08 mg g-1 at its maximum, being higher than majority previously reported adsorbents. In adsorption, kinetic process closely followed pseudo-second model, thermodynamic discovered be exothermic spontaneous nature. exhibited excellent physicochemical stability, facile recovery acceptable recyclability properties. Moreover, synergistic interactions between mainly involved electrostatic forces, hydrogen bonding, π-π stacking, chelation. Within benefits low cost, ease performance, biosorbent shows promising utilization removing contaminants from wastewater.
