Bisphenol A was efficiently adsorbed on biochar magnetically modified with microwave‐synthesized magnetic iron oxide particles. The adsorption followed the Langmuir isotherm model, and the maximum adsorption capacity was 77.4 mg per gram of magnetic biochar at 282.15 K. Kinetics of sorption process followed the pseudo‐second‐order kinetic model, and thermodynamic studies described an exothermic and spontaneous adsorption process. The prepared material exhibited high adsorption of bisphenol A and a rapid magnetic response to an external magnetic field.
