چکیده:

In this work Fe3O4 nano-particles have been synthesized by co-precipitation method. This nano-particles have been functionalized by amine group using 3-Amino propyl triethoxy silane and characterized by X-ray powder diffraction (XRD), infrared (IR) spectroscopy, scanning electron microscopy (SEM), thermal (TGA-DSC) and elemental analyses. Application of these magnetic nano-particles was investigated in heavy metal determination and removal. Effects of several parameters such as the sample pH, eluent type and concentration and also maximum adsorption capacity of functionalized mesoporous in removal and determination of heavy metals have been studied.
