摘要 饮用水中的重金属是给水处理面临的主要问题之一.以油酸为功能单体,二乙烯基苯为交联剂,乙腈为溶剂,应用反相微乳液聚合方法,制备了Fe(Ⅲ)印迹聚合物微球.运用扫描电子显微镜、红外光谱仪和比表面积测定仪等进行了该印迹聚合物微球的表征.研究表明:该聚合物微球外观形貌和内部孔隙清晰分明,具有较大的比表面积和孔体积,对水中的重金属Fe(Ⅲ)具有良好的识别和吸附性能. The pollution of heavy metal ions in drinking crospheric Fe( Ⅲ) imprinted polymer was synthesized water is a main problem in feedwater treatment. Miusing oleic acid as functional monomer and divinylbenzene as cross -linker by the inverse micro-emulsion polymerization approach. And fourier transform-infrared spectra( FT- IR), the scanning electron microscopy(SEM) and an autosorb instrument were employed to characterize it structure. Furthermore, the adsorptive capacity of microspheric Fe( Ⅲ ) imprinted polymers was tested in drining water. The test results showed that the microspheric Fe (Ⅲ ) imprinted polymers had good ad- sorptive capacities for Fe ( Ⅲ ).
