Magnetic Hyperthermia Investigation Of Cobalt Ferrite Nanoparticles

The effect of magnetic hyperthermia on dissolution of cobalt ferrite nanoparticles in distilled water was investigated. Synthesis of cobalt ferrite nanoparticles (CoFe2O4) was performed by Co-precipitation method at 80 ° C, with precursor including iron and cobalt salts in the presence of air atmosphere. CTAB was used as a surfactant in this synthesis. The particle structure and morphology as well as the structure and magnetic properties of these nanoparticles were studied by X-ray diffraction (XRD) field emission scanning electron microscopy (FESEM) and vibrational sample magnetometer (VSM), respectively. Sample magnetic hyperthermia was measured after preparation of ferrofluid with a concentration of 3 mg/ml in distilled water and in an ac magnetic field with a frequency of 400 kHz and a field intensity of 400 Oe. The increase in sample temperature over time was determined and its specific heat dissipation power (SLP) was measured. According to the measurement results, the sample SLP was 151 W/g.
