在乙醇溶液中,以Cu(Ⅱ)为模板分子,二甲基丙烯酸乙二醇酯为交联剂采用分散聚合法制备铜离子印迹聚合物(Cu~(2+)-IIP),并通过傅里叶变换红外光谱、紫外光谱对聚合物的结构及性能进行了表征。考察了吸附时间、溶液初始浓度、pH值等因素对聚合物吸附性能的影响。实验表明,室温条件下,在pH=6,90min吸附达到平衡,其最大吸附量为1.42mmol/g;与非印迹聚合物相比,印迹聚合物有较大的吸附量及较好的选择性。因此,印迹聚合物在固相萃取、水处理等方面具有很好的应用前景。
Copper ion imprinted polymer (Cu ~ (2 +) - IIP) was prepared by dispersion polymerization using Cu (Ⅱ) as template and ethylene glycol dimethacrylate as crosslinking agent in ethanol solution. Fourier transform infrared spectroscopy, UV spectroscopy of the structure and properties of the polymer were characterized. The effects of adsorption time, initial concentration of solution, pH and other factors on the adsorption properties of the polymer were investigated. Experiments show that at room temperature, pH = 6, 90min adsorption equilibrium, the maximum adsorption capacity of 1.42mmol / g; Compared with non-imprinted polymer, the imprinted polymer has a larger adsorption capacity and better selectivity . Therefore, the imprinted polymer has good application prospects in the aspects of solid phase extraction, water treatment and the like.
