The chemistry of transition metal chalcogenides are good candidates in material science due to their vast applications. Various synthetic strategies can be used to adjust the morphology, shape and size of material. Fe3O4 is a wide bandgap (2-3 eV) material and it has a wide range of uses, including those for drug delivery systems, magnetic resonance imaging (MRI), as a catalyst and as data storage material. There are 35 metals that are of concern for us because of residential or occupational exposure, out of which 23 are there. The Cadmium is a heavy metal which has considerable toxicity with impact on most organs. Long-term exposure to cadmium through air, water, soil, and food will leads to cancer and organ system toxicity such as skeletal, urinary, reproductive, cardiovascular, central and peripheral nervous, and respiratory systems. Cadmium levels can be measured in the blood, urine, hair, nail and saliva samples. Cd binds to DNA and impair vitamin D. It is also responsible for oxidative stress. Herein, we demonstrate preparation of Fe3O4 nanoparticles using Tris(acetylacetonato) ironIII. The complex was characterised by UV-vis and FTIR. The complex was used as single source precursor for preparation of Fe3O4 nanoparticles. The brown colour powder was characterized by powder XRD, SAED and TEM. The powder XRD shows (220) (311) (222) (422) (311) with cubic phase which matches with (JCPDS 19-0629). TEM image shows particles size from 20-30. Further, the prepared Fe3O4 nanoparticles shows Adsorption Cd in acidic pH which can subsequently be eliminated.
