Development of iron oxide nanoparticles-based magnetic carbonaceous nanocomposites for removing of radionuclides from contaminated water

This research proposal focuses on developing innovative iron oxide nanoparticles-based magnetic carbonaceous nanocomposites for the effective removal of radionuclides from contaminated water. The study addresses the critical need for efficient, sustainable, and cost-effective materials to mitigate the environmental and health hazards associated with radionuclide contamination. The proposed research aims to synthesize magnetic nanocomposites by integrating iron oxide nanoparticles with carbonaceous materials, such as graphene oxide or activated carbon. These materials will be engineered to combine the superior adsorption properties of carbonaceous materials with the magnetic separability of iron oxide nanoparticles. The resulting nanocomposites are expected to offer high adsorption capacity, rapid separation, and reusability.

The research will involve systematic synthesis and characterization of the nanocomposites using advanced techniques like X-ray diffraction (XRD), scanning electron microscopy (SEM), transmission electron microscopy (TEM), X-ray photoelectron spectroscopy (XPS), Fourier transform infrared (FTIR) and Raman spectroscopy as well. Subsequently, their performance will be evaluated for the removal of radionuclides, such as uranium or strontium or cesium, under varying environmental conditions (e.g., pH, temperature, and competing ions). The study will also explore the underlying adsorption mechanisms through isothermal, kinetic, and thermodynamic analyses.

By optimizing the material properties and adsorption conditions, this project seeks to develop a scalable and practical solution for radionuclide removal. The outcomes could significantly contribute to environmental remediation strategies, particularly for nuclear waste management and the treatment of contaminated water sources. This research has the potential to advance the field of nanotechnology for environmental applications by providing a robust, eco-friendly, and efficient method for addressing radionuclide contamination challenges.
