In this day and age, the excessive use of antibiotics for medical purposes has resulted in antibiotic pollution, which has negative impacts on human health and the environment. Biochars originated in pine leaves (P.kesiya) and rice husk were pyrolyzed to remove tetracycline from aquatic environments. Utilizing physical analysis methods (BET, FT-IR, SEM, and EDX) to determine materialcharacterizations and factors (pH, contact time, initial tetracycline concentration) affecting adsorption efficiency. The adsorption processes of tetracycline onto biochars were fitted by the Langmuir isotherm model. Additionally, the kinetic data of adsorption processes were well-described by the pseudo-second-order model. The maximum adsorption capacities of tetracycline onto biochars originated in pine leaves (P.kesiya) and rice husk were 21,44 and 21,37 mg/g, respectively. Biochars originated in pine leaves (P. kesiya) and rice husk will be potential materials to adsorb antibiotics from aquatic environments.
