Abstract

In this paper, Fe3O4@SiO2 core/shell magnetic NANOSTRUCTURE has been synthesized and modified by N- (2-aminoethyl) -3-aminopropyltrimethoxysilane (AEAPTMS). Fe3O4@SiO2 was used as a novel adsorbent for separation of hexachloroplatinic acid.X-ray diffraction (XRD), scanning electron microscopy (SEM), and FT-IR technique were used to characterize morphologies and surface texturing of this adsorbents. The effective factors on ADSORPTION, such as pH, contact time; salt effect and temperature were studied systematically. The optimal conditions of PLATINUM ADSORPTION were obtained at temperature of about 25oC, pH about 2.5 and the equilibrium time of 30-40 minutes. The maximum ADSORPTION capacity (qmax) in the optimal conditions was equal to 74mg/g. The MAGNETIC SEPARATION of the absorbent was achieved by a magnet and finally the absorbent was compared with other absorbents. Inductive coupled plasma optical emission spectrometer (ICP-OES) was used for determination of metal ion concentrations in the aqueous solution.
