Synthesis and Investigation of CuFe2O4-Al2O3 Magnetic Nanocomposite in Order to Remove Methyl Red and Methyl Orange Toxic Pollutants from Aqueous Solutions

In this research, magnetic and photocatalytic nanoparticles of copper ferrite were synthesized using hydrothermal methods. the synthesis was repeated in the presence of ultrasound waves to determine the effect of these waves on the nanostructure of the materials. photocatalytic property of copper ferrite was investigated in the degradation of two toxic dyes, methyl orange and methyl red under uv- ir radiation. due to magnetic property of copper ferrite nanoparticles, they have the ability to direct photocatalytic reaction products out of the reaction environment too. on the other hand, aluminum hydroxide and aluminum oxide nanoparticles were also synthesized by the same method. aluminum oxide nanoparticles with high porosity are very suitable absorbents for color absorption. finally, a core-shell magnetic nanocomposite was made with copper ferrite, alumina and aluminum hydroxide absorbers with hydrothermal method assisted by ultrasound waves and the photocatalytic potential of prepared nanocomposite was assessed using acidic ph methyl orange and methyl red solutions under uv- ir radiation. also all of products were analyzed by x-ray diffraction (xrd), scanning electron microscope (sem) and vibrating sample magnetometry (vsm).
