Abstract

Using 3-aminopropyltriethoxysilan (APTES) to modify the interior surface of SBA-15 channels, PAMAM of generation 1 and generation 2 were successfully grafted in the meso-channels of SBA-15. The PAMAM-SBA-15 hybrids are employed in the adsorption of heavy metal ions to determine their adsorptive capacity, with the APTES modified SBA-15 as a reference sample. The bonding between PAMAM hybrids and metal ions are proved to be much stronger than that of APTES modified SBA-15 by TG-MS tests. Hybrids are used in deposition solution containing several kinds of heavy metal ions, and the selective adsorption of Pb²⁺ and Zn²⁺ is found. After deposition, the concentrations of Pb²⁺ and Zn²⁺ are reduced to 0.003mg/L and 0.037mg/L, respectively, which are lower than the national standard of drinking water.
