Fabricated a novel magnetic hydrogel nanocomposite from xanthan gum for removal of Cu(II) from water and waste water samples

Following industrialization and urbanization, water pollution by heavy metals is the most important environmental problem in the world, therefore, today, water and wastewater treatment to remove heavy metals has received more attention to reduce serious risks for humans and living organisms. In the present study, A novel magnetic hydrogel nanocomposite was synthesized by modifying Xanthan Gum (XG) with polyacrylamide and polyacrylic acid as homopolymer and magnetic iron oxide nanoparticles (MNPs Fe3O4) for the removal of Cu(II) from water and wastewater samples. The magnetic hydrogel nanocomposite was characterized by Fourier-transform infrared spectroscopy (FT-IR), X-ray diffraction (XRD), and scanning electron microscopy (SEM). The relevant parameters on adsorption were optimized. Isotherm models were studied and the maximum adsorption capacities of Cu (II) was 160.2 mg/g and the adsorption proses controlled by pseudo-second-order kinetic. Finally, the magnetic hydrogel nanocomposite exhibited high performance for the removal of Cu (II) from water and waste water samples.
