Structural, optical, magnetic, photocatalytic activity and related biological effects of CoFe2O4 ferrite nanoparticles

The synthesis of magnetic nano-sized spinel ferrites has become an important area research, due to their several potential applications. In this work, CoFe2O4 nanoparticles were synthesized by the co-precipitation method. Structural, magnetic, and photocatalytic properties cobalt analyzed based on chemical composition considering biological properties. Structural morphological investigated X-ray diffraction analysis (XRD) scanning electron microscope (SEM), respectively. Lattice parameters cell volumes calculated from XRD data. SEM images revealed uniform surface morphology spherical shape nanoparticles. Magnetization measurements measured using Lake Shore 7304 model Vibrating Sample Magnetometer (VSM). hemolytic activity tests, formation a precipitate with characteristic black color provided explicit evidence heme–iron complexes. Undesirable effect human erythrocytes at both concentrations was attributed comparatively high amount reactive oxygen species formed theoretical concentration Co (theory) obtained second-order (0.82 mg/L) fit experimental value (experimental) (0.95 well in tests.
