Synthesis of Magnetic Ni 0.3 Mg 0.3 Zn 0.4 Fe2O4 Nanoparticles and Their Adsorption Performances of Congo Red.

摘要: Magnetic Ni0.3Mg0.3Zn0.4Fe₂O₄ nanoparticles were synthesized by the absolute alcohol combustion method. The morphology, microstructure, and composition of as-prepared characterized several techniques: vibrating sample magnetometer (VSM), scanning electron microscopy (SEM), X-ray diffraction (XRD), energy dispersive spectroscopy (EDS). experimental results showed that calcination temperature solvent volume crucial factors for synthesis magnetic nanoparticles. adsorption performance congo red (CR) was investigated. model pseudo-second-order kinetic optimal matching obtaining parameters CR in initial range 100-400 mg/L-1, while, isotherm data onto could conform to Temkin owing values square deviations, which revealed at room monolayer multilayer mechanism.
