Abstract

In this study, carboxymethyl chitosan bound Fe3O4 magnetic nanoparticles (CC-Fe3O4 NPs) was synthesized by the binding of carboxymethyl chitosan (CC) onto the surface of Fe3O4 magnetic nanoparticles, which was prepared by coprecipitating method. The CC-Fe3O4 nanoparticles was characterized by transmission electron microscopy (TEM), X-ray diffractometer (XRD), vibrating sample magnetometer (VSM), Nucleus Magnetic Resonans (NMR) and Fourier Transform Infra Red (FTIR). TEM studies confirmed that the Fe3O4 and CC-Fe3O4 particles have a particle size ranges from 9.73-12.30 nm and 9.70-12.50 nm, respectively. The magnetic properties of the Fe3O4 particles were verified using VSM. Their saturation magnetization, remnant magnetization and coercivity were 61.0 emu/g, 2.70 emu/g and 38.20 G, respectively. FTIR studies showed the appearance of peaks at 1629 cm-1 and 1397 cm-1 which were characteristic of COOM (M = metal ions) bands, indicating the formation of the iron carboxylate.
