Abstract
The magnetic and sorption properties of CoFe2O4 and SiO2 nanocomposites were studied. Composite samples were prepared by precipitation and impregnation using silica of plant or mineral origin. X-ray powder diffraction and IR spectroscopy showed that the composites comprise both amorphous SiO2 and 5.3–59.2% CoFe2O4. The sorptive capacity for methylene blue (8.8–26.7 mg/g) was higher than that of the precursor SiO2. All composites studied were ferromagnetic at room temperature. Their saturation magnetizations increased from 1.2 to 29.0 emu/g as the cobalt ferrite concentration in them increased.
