2-(ureylene-methyl)pyridine Imprinted Periodic Organosilica for Selective Adsorption of Target Metal Ions from Water and Seawater |
| 초록 |
2-(ureylene-methyl)pyridine imprinted periodic mesoporous silica has been synthesized via surfactant assisted sol-gel methodology from a chemically synthesized organopolysilane precursor with a metal template (Co2+ ion) imprinted ligand centre with tetraethylorthosilicate and cetyltrimethylammoniumbromide as a structural directing surfactant under basic conditions. The imprinted metal template was easily leached out from the hybrid materials during an acid treatment, which resulted in a template-free ion-imprinted network in the PMO pore wall framework with an unaltered particle size and morphology. Furthermore, the removal of the imprinted metal template was confirmed by inductively coupled plasma-atomic emission spectroscopy. The selective rebinding ability of the template ions on the ion-imprinted PMO hybrid adsorbents was examined using a cobalt nitrate solution. The rebinding results showed excellent efficiency towards Co2+ ions from water as well as sea water. |
