Hydrogenation Reduction of Organic Dyes by Noble Metal /Fe3O4 Nanoparticles Anchored on Nanocellulose

Abstract

The object of this study was to evaluate the discolorization efficiency of sunset yellow (SY) anionic dye from aqueous solutions by using new noble metal /Fe₃O₄ nanoparticles anchored on nanocellulose. Ag/Fe₃O₄@PEI nanoparticles (NPs) were synthesized through a solvothermal method. The prepared magnetic nanoparticles were added to nanocellulose dispersion to obtain Ag/Fe₃O₄@PEI/CNCs nanocomposite by the self-assembled method. The discolorization process, of SY dye, by Ag/Fe₃O₄@PEI/CNCs nanocomposite, was investigated in the time. The small amount of this nanocomposite (5 mg) is applicable for the removal of high concentrations of SY dye in 8 min. The nanocomposite showed high stability for the 5^th cycle of the discolorization reaction.
