In this work, BSEA-SBA-15 was prepared for the first time, which was prepared by covalently anchoring Schiff-base compound (N,N´-bis(salicylidene)ethylenediamine (BSEA) on SBA-15 by hydrothermal method. The structure and physicochemical properties were determined by elemental analysis, XRD, nitrogen adsorption–desorption, thermogravimetric analysis and FTIR spectroscopy, SEM, BET surface area and BJH pore size. The average pore diameter after the modification is 69Å. It is expected that BSEA-SBA-15 can be used as an effective adsorbent for the removal of metal ions due to having porous structure and active functional groups.
