Fe3O4 MNPs and gum xanthan based hydrogels nanocomposites for the efficient capture of malachite green from aqueous solution

Herein we report effective removal of malachite green (MG) from aqueous solution using gum xanthan (Gx)/Fe3O4 magnetic nanoparticles (MNPs) filled hydrogel nanocomposites. Gx-cl-P(AA-co-AAm)/Fe3O4 hydrogel nanocomposite was fabricated via incorporating Fe3O4 magnetic nanoparticles within the polymer matrix of the hydrogel of gum xanthan with co-polymer mixture of poly(acrylic acid-co-acrylamide). Maximum adsorption was observed in the solution...
