Applications of Rare Earth Metal Ion-Embedded Nano Ferrites in Dye Removal from Water

Nano-ferrites are proved to be a powerful and commendable material nowadays for removal of hazardous pollutants from waste water. Incorporation of rare earth metal ions into these metal ferrites alters the characters of specific metal nano-ferrites. In this study, Lanthanum doped (x=0,0.1,0.3,0.5) cobalt ferrites (CoLaxFe2-xO4) were prepared via sol-gel synthesis. Synthesized doped nano-ferrites were characterized through FTIR, XRD (26.74 nm, 7.66 nm, 39.57 nm and 2.12 nm), SEM-EDX and SEM techniques. The impact of incorporation of lanthanum ions on adsorption efficiency of different nano-ferrites material was checked to the adsorption of methylene blue dye and Rhodamine B dye and the results were compared.
