چکیده
In this study MCM-41, Fe20-MCM-41 and Fe40-MCM-41 mesoporouse silicates have been prepared in various conditions with cetyltrimethylammonium bromide (C16) and dodecyltrimethyl-ammonium chloride as template and various mole ratios of Si/Fe. The resulted compositions have been characterized by power X-ray diffraction, N adsorption–desorption measurements and Fourier transform infrared spectroscopy (FT-IR). 2 The Pb(II) adsorption of the MCM mesoporous type has been studied and the effect of Fe has been considered as promoter in adsorption process. Adding Fe in the MCM-41 composition has been improved some heavy metal ions adsorption considerably. Finally this adsorbents was applied to removal of Pb(II) from waste water samples.
