Abstract

In the present work, the anticancer, photocatalytic and magnetic qualities of nanocrystalline nickel or magnesium-doped nanoparticles of lithium-ferrite samples, formed through sol-gel auto-combustion process were investigated. The products were studied by FT-IR spectroscopy, scanning electron microscopy (SEM), energy dispersive X-ray (EDX) technique, X-ray diffraction (XRD), ultraviolet-visible diffuse reflectance spectroscopy (DRS), photoluminescence (PL) spectra, and vibrating sample magnetometery (VSM). XRD results showed that the nano-photocatalytic samples lithium ferrite (Li0.5Fe2.5O4), lithium-magnesium ferrite (LiMg0.5Fe2O4) and lithium-nickel ferrite (LiNi0.5Fe2O4) are nano-photocatalytic samples, which are in good crystalline form. The LiMg0.5Fe2O4 nano-photocatalyst showed the highest photocatalytic performance for removal of methyl orange (MO) and removed 99.9 of pollutant within 25 min under ultraviolet (UV) light irradiation. Magnetic characterization revealed that the M-r and M-s of LiNi0.5Fe2O4 nano-photocatalyst decreases with doping Ni or Mg. Finally, in vitro cytotoxic effect of synthesized nanoparticles was evaluated on Hela cell line.
