چکیده

In this paper, a rapid and room temperature electrochemical method is introduced for preparation of Ni doped iron oxide nanoparticles (Ni-IONs) grafted with ethylenediaminetetraacetic acid (EDTA) and polyvinyl alcohol (PVA). EDTA/Ni-IONs and PVA/Ni-IONs samples were prepared through base electro-generation on the cathode surface from aqueous solution of iron(II) chloride, iron(III) nitrate and nickel chloride salts with EDTA/PVA additive. Uniform and narrow particle size Ni-IONs with an average diameter of 15 nm was achieved. Ni doping into the crystal structure of synthesized IONs and also surface grafting with EDTA/or PVA were established through FT-IR and EDAX analyses. The saturation magnetization values for the resulting EDTA/Ni-IONs and PVA/Ni-IONs were found to be 38.03 emu/g and 33.45 emu/g, respectively, which proved their superparamagnetic nature in the presence of applied magnetic field. The FE-SEM observations, XRD and VSM data confirmed the suitable size, crystal structure and magnetic properties of the prepared samples for uses in biomedical aims
