【摘要】：以8-羟基喹啉和四氯化锗为模板,采用杂化沉淀聚合法制备了8-羟基喹啉锗印迹聚合物微球MIPs,并对其微观结构及孔径分布进行表征,推测了8-羟基喹啉锗印迹聚合物合成过程,对MIPs对锗离子的吸附性能进行了研究。结果表明,MIPs具有大比表面积(170.32m~2/g)、微观多孔的纳米微球结构。吸附时间延长、溶液中初始锗含量提高,MIPs对锗离子的选择性吸附能力提高,当吸附时间2h、溶液中初始锗浓度为0.5mg/mL时,MIPs对锗的吸附率达到最大96.84%,MIPs对锗离子具有显著吸附选择特性。
[Abstract]:Using 8-hydroxyquinoline and germanium tetrachloride as templates, 8-hydroxyquinoline germanium imprinted polymer microspheres MIPswere prepared by hybrid precipitation polymerization. The microstructure and pore size distribution of 8-hydroxyquinoline germanium imprinted polymer were characterized, and the synthetic process of 8-hydroxyquinoline germanium imprinted polymer was inferred. The adsorption of germanium ion by MIPs was studied. The results show that the MIPs have a large specific surface area of 170.32mg / g and microporous nanospheres. When the adsorption time was prolonged, the initial content of germanium in the solution increased the selective adsorption of germanium ion. When the adsorption time was 2 h and the initial concentration of germanium in the solution was 0.5mg/mL, the adsorption rate of germanium reached the maximum of 96.84%.
