Abstract Nanomaterials, especially ferrites, have various applications in mechanical, electrical, and optical fields. However, their abilities environmental remain unexplored. In this work, the flash auto-combustion method has been used to prepare three different compositions of CuFe 2 O 4 , Zn-CuFe Co-CuFe nanocomposite. The structure, spectroscopic, surface, morphological properties prepared samples were characterized using XRD, FTIR, BET, HRTEM, respectively. According XRD analysis, ferrites consist nanocrystalline particles with sizes 24.5, 37.5, 32.6 for Zn-CuFe2O4, Co-CuFe2O4, had a single cubic phase, while tetragonal phase was formed . addition cobalt zinc copper ferrite increased crystallite size lattice parameters. absorption band FTIR spectra, which represents stretching vibrations along [MetalO] bond at octahedral (B) position, nearly constant (412 Cm −1 ) by Zn CuFe2O4. surface area quantity gas adsorbed on Co-CuFe2O4 highest. greatest force constants [(Ko = 1.37 & KT 1.32 105 dyne/cm] detected Co-CuFe2O exhibited highest saturation magnetization as well magnetocrystalline anisotropy.

Abstract A graphene-based Sm-doped Co-ferrite CoSmFe-G nanosample was created using the citrate auto-combustion method. It acts as an antibacterial agent and heavy metal remover. The sample’s physical properties were analyzed various techniques including X-ray diffraction (XRD), Fourier transform infrared spectroscopy (FT-IR), Raman spectroscopy, scanning electron microscopy (FE-SEM), zeta potential, vibrating sample magnetometer (VSM) measurements. XRD results confirmed presence of a single-phase cubic spinel structure. experimental indicated that doping with graphene samarium significantly altered magnetic nanoparticles, reducing saturation magnetization (MS) values to 35.759 emu/g. showed against both gram-positive gram-negative bacteria, inhibition zones measuring 12–14.5 mm in diameter. Additionally, exhibited efficient (Pb 2+ ) adsorption, maximum removal capacity 99.8% multilayer adsorption mechanism by pseudo-second-order isotherm Freundlich model matching. study explores binding interactions for lead highlights potential (CoSmFe-G) nano samples bio-adsorbent agent. This could practical solutions water disinfection.
