Abstract

Magnetic Ni0.5Zn0.5Fe2O4/SiO2 nanocomposites were prepared via the solution combustion process, their structure and magnetic properties were investigated by XRD, SEM, TEM and VSM. The asprepared magnetic Ni0.5Zn0.5Fe2O4/SiO2 nanocomposites were characterized with the average grain size of about 20 nm, the specific magnetization of 31.6 Am2/kg, and the specific surface area of 117.0 m2/g. The adsorption kinetics of bovine serum albumin (BSA) from aqueous solution onto the magnetic Ni0.5Zn0.5Fe2O4/SiO2 nanocomposites at room temperature was investigated. The kinetics data related to the adsorption of BSA from aqueous solutions were in good agreement with the pseudo-second-order kinetics model in the initial concentrations of 0.2-0.8 mg/mL.
