Modified Mesoporous Silica Preparation and Its Adsorption Properties on Heavy Metal Ions

摘要：

　　This thesis aims to synthesize multi-level modified mesoporous silica materials and investigate the preparation and application of amino-modified mesoporous silica.We use mesoporous silica as the original material and directly graft 3-aminopropyl triethoxysilane(APTES) to its surface.Then the characterization of modified mesoporous silica is analyzed.So we try to investigate the selective adsorption characteristics of mesoporous silica adsorbent and amino-modified mesoporous silica adsorbent on heavy metal ions such as Cd2+, Pb2+.The effects ofpH(initial and final state value), temperature and the initial concentration of heavy metal ions on the adsorption capbility of mesoporous adsorbent are also analyzed.Finally, we compared mesoporous silica adsorbent with amino-modified mesoporous silica and find that amino-modified mesoporous silica has a better adsorption capbility than mesoporous silica adsorbent.
