Wastewater treatment using various separation processes is necessary. Conventional methods of water treatment, like filtration, are insufficient when compared to techniques such as membrane separation and adsorption. Adsorption was found to be a preferable choice for the removal of metal ions owing to its simplicity.

Carbon-based materials are widely used in water treatment. It is often physiochemically modified to enhance their mechanical stability, durability and surface properties. Ferrites of the formula MFe2O4 (M is a divalent metal cation) are very promising materials. Ferrites will be considered in this project because of their low cost, high activity, and efficient recyclability and reuse. They are used in different applications including biomedicine, gas sensors, super magnetic materials, microwave technology, and hydrogen production. Their chemical and physical properties can be adjusted by using proper routes for the synthesis. Various methods can be used to prepare ferrite materials such as microwave, hydrothermal, sol-gel, and co-precipitation methods.
This work will investigate the adsorptive properties of various MFe2O4-carbon nanocomposites for the removal of Pb2+ and Cd2+ from aqueous solutions. The results of adsorption experiments will be used to determine the material of the highest adsorption capacity.

Expected outcome from the Student's work
  1. Prepare selected MFe2O4-carbon nanocomposites using different techniques such as hydrothermal and sol-gel methods.
  2. Characterize the nanocomposites using XRD, FTIR, SEM, and TGA techniques.
  3. Determine the most efficient composite for the removal of Pb2+ and Cd2+ from aqueous solutions.
