| Abstract: |
| Microspheric 8-hydroxyquinoline-germanium ion imprinted polymer (MIPs) was prepared by hybrid precipitation polymerization method with 8-hydroxyquinoline and germanium tetrachloride as template. Microstructure and pore size distribution of MIPs were characterized. Synthesis process of imprinted polymer was speculated. Adsorption performance of MIPs was analyzed. The results show that MIPs has large specific surface area (170.32 m2/g), and micro porous nanometer microspheres structure. Selective adsorption ability of MIPs for germanium ion is improved with increase of adsorption time and initial germanium content in solution. Adsorption rate of germanium with MIPs is 96.84% under the conditions of adsorption time of 2 h and initial concentration of germanium of 0.5 mg/mL. MIPs has remarkable selective adsorption ability for germanium ion. |
