Abstract

Mesoporous silica is an important material which has various industrial applications. Currently, it is produced from precursors that are costly. Mesoporous silica with pores of ordered 1-dimensional hexagonal structure MCM-41was synthesized under basic media using sugar cane ash as silica precursor and cetyltrimethylammoniumbromide(CTAB) as surfactant. For the sake of simplicity ; iron(II,III) oxide (FeO.Fe2O3)  was used in the synthesis of a new generation of modified MCM-41. The expanded material was prepared by modification with dimethylglyoxime (dmg) and it was tested for adsorption of Ni(II)  in aqueous solution. It was found that the modified magnetic MCM-41 has a very high capacity for adsorption of heavy metals.
