Magnetic Fe3O4@C nanoparticles were synthesized via a solvothermal approach by reaction of Fe(acac)3 ,sucrose and Na2CO3 .The composition,morphology and size of magnetic Fe3O4@C nanopar-ticles were characterized by X-ray diffraction (XRD)and scanning electron microscopy (SEM).The ab-sorption and release behaviors of the Fe3O4@C nanoparticles toward kanamycin were investigated sys-tematically.The results revealed that magnetic Fe3O4@C nanoparticles had excellent performance in drug absorption and release.
