Magnetic ZnFe2O4 nanoparticles were prepared by the rapid combustion process, their structure and magnetic properties were investigated by XRD, SEM, TEM and VSM. The as-prepared magnetic ZnFe2O4 nanoparticles were characterized with the average grain size of about 18 nm, the specific magnetization of 3.1 Am-2/kg, and the specific surface area of 53.3 m(2)/g. The adsorption kinetics and adsorption isotherms of bovine serum albumin (BSA) in aqueous solution onto the magnetic ZnFe2O4 nanoparticles at room temperature were investigated. The kinetics data related to the adsorption of BSA from aqueous solutions were in good agreement with the pseudo-first-order kinetic model in the initial concentration of 0.4-1.2 mg/mL. Compared with the Langmuir, Freundlich and Redlich-Peterson models for adsorption isotherms of BSA, the Temkin model (correlation coefficient R-2 = 0.9977) could be used to evaluate BSA adsorption isotherm at room temperature.
