摘要
以聚苯乙烯为种球,以铜绿微囊藻毒素(MC-LR)为模板分子,甲基丙烯酸(MAA)为功能单体,N′,N-亚甲基双丙烯酰胺为交联剂,通过溶胀聚合法得到分子印迹聚合物微球。采用电子显微镜、孔隙度分析、红外吸收等对其进行表征。并对制备铜绿微囊藻毒素分子印迹聚合物进行了优化条件实验(单体/模板/交联剂质量比为2660∶1∶3947;洗脱时间25 min)。通过Scatchard吸附模型分析,计算得离解常数Kd为3.7μmol/L,最大表观吸附量Qmax为124.7μg/g。
With polystyrene as ball,microcystins(MC-LR)as template molecule,methyl methacrylate(MAA)as functional monomers,N′,N-methylene double acrylamide as crosslinking agent,molecularly imprinted polymer microspheres were prepared by swelling polymerization.The microspheres were characterized with electron microscopy,porosity analysis,and infrared absorption,Optimized experimental conditions of the microcystins molecularly imprinted polymer mass ratio were monomers∶template∶crosslinking agent=2600∶1∶3947;elution time was 25 min.By Scatchard curve analysis,the dissociation constants Kd was 3.7 μg/mL,maximum apparent adsorption Qmax was 124.7 μmoL/g.
