Green synthesis of magnetic nanocomposite by Cordia Africana (CA) leave extract for the treatment of Methylene blue contaminated water

The magnetic behavior of individual magnetite (Fe3O4) nanoparticles (MNPs) has arisen considerable attention in environmental application. However, magnetic properties and stability weaken due to their high susceptibility to chemical activity (oxidation). Efforts have increasingly been made to encap...
