Abstract
Nano-magnetic particles play an important role in the field of bio-separations and biomedical applications. Due to their size, nanoparticles provide large area for adsorption of solutes by magnetic field. The objectives of this research were synthesizing magnetite nanoparticles (Fe3O4) and determining its efficiency in phenylalanine extraction from aqueous solutions. In this study two different methods were used to synthesize magnetite nanoparticles (Fe3O4). The first one was typical co-precipitation method by Fe+2 and Fe+3 salts in alkaline medium and the latter was a micro-emulsion method in which the effect of a new surfactant upon adsorption rate of phenylalanine on nano-magnetic particles (Fe3O4) has been studied. Consequently, the effect of pH, contact time and concentration of phenylalanine were investigated in a batch system. Transmission electron microscopy (TEM), XRD and FTIR were used for characterization of the synthesized magnetite nanoparticles.
