Mesoporous silica SBA-15 without and with modification of surface by grafting with aminoalcoxysilanes is prepared is the experiment. The prepared samples are characterized by adsorption/desorption of nitrogen. Results confirms the prepared materials having a specific surface area up to 846m2/g, which are improved for the capture of metals by grafting with the amino group. The sorption of Cu2+ cations as well as SO42− anions from the acidic solution is investigated. The modified mesoporous silica is confirmed to have better sorption capacity than unmodified mesoporous silica.
