Synthesis and Characterization of Functionalized SBA-15 Mesoporous Silica by N, N´-Bis(salicylidene)ethylenediamine Schiff-Base

In this work, bsea-sba-15 was prepared for the firsttime, which was prepared by covalently anchoring schiffbasecompound (n,n´-bis(salicylidene)ethylenediamine(bsea) on sba-15 by hydrothermal method. thestructure and physicochemical properties were determinedby elemental analysis, xrd, nitrogen adsorption–desorption, thermogravimetric analysis and ftirspectroscopy, sem, bet surface area and bjh pore size.the average pore diameter after the modification is 69?. itis expected that bsea-sba-15 can be used as an effectiveadsorbent for the removal of metal ions due to havingporous structure and active functional groups.
