چکیده:

In this work amine functionalized MCM-41 mesoporous silica have been synthesized and characterized by X-ray powder diffraction (XRD), infrared (IR) spectroscopy, transmission electron microscopy (TEM), thermal (TGA-DSC) and elemental analyses. Application of functionalized mesoporous silica 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
