Cu(Ⅱ)离子印迹聚合物微球制备及其性能

Preparation and Property of Microspheric Cu(Ⅱ) Ion Imprinted Polymer

饮用水中的重金属是给水处理面临的主要问题之一。以甲基丙烯酸(MAA)为功能单体,乙二醇二甲基丙烯酸酯(EDGMA)为交联剂,甲苯为溶剂,应用反相微乳液聚合方法,制备了Cu(Ⅱ)离子印迹聚合物微球。运用扫描电子显微镜和红外光谱仪等对该印迹聚合物微球进行表征,表明该聚合物微球外观形貌和内部孔隙清晰分明,对水中的重金属Cu(Ⅱ)离子具有良好的识别和吸附性能。

The pollution of heavy metal ions in drinking water is a main problem in feedwater treatment. Microspheric Cu（Ⅱ） ion imprinted polymer is synthesized using methacrylic acid as functional monomer and ethylene glycol dimethacry- late as cross--linker by the inverse micro--emulsion polymerization approach. And fourier transform--infrared spectra （FT--IR） and the scanning electron microscopy（SEM） are employed to characterize it structure. Furthermore, the ad- sorptive capacity of microspheric Cu（Ⅱ） ion imprinted polymers is tested in drinking water. The test results show that the microspheric Cu（Ⅱ） ion imprinted polymers have good adsorptive capacities for Cu（Ⅱ） ion.
