Abstract
Magnetic nanoparticles (MNPs) of iron were prepared in a single stage reaction with citric acid through a reduction process. Iron (III) acetylacetonate Fe (acac)3 were used as precursors for the synthesis of Fe3O4 nanoparticles. Elemental analyses of the produced magnetic Fe3O4 particle was carried out by energy dispersive analysis of X-ray (EDAX) method. The particle size of nanoparticle was analyzed by transmission electron microscopy and XRD data using Scherrer’s equation and Williamson-Hall plot. Magnetic saturation of the nanoparticles was determined through vibrating sample magnetometer (VSM). XRD and selective area electron diffraction (SAED) pattern confirm the formation of well-crystallized Fe3O4 particles. Transmission electron microscopy confirms the formation of nanoparticles with the average particle size in the range of 18–34 nm. The average size of the particles decreases with an increased annealing temperature of the gel. Thermal properties of the formed particle were studied through thermogravimetric technique (TGA).
